Paul Hegarty - Consignment Specialist Message Paul

“ Pint Sized Marvel - 1 of only 1050 and highly sought after by Mini Enthusiasts. ”

Launched on 10th July 1990, the MINI Cooper RSP (Rover Special Products) marked a special edition for the Rover Cooper line. To commemorate the first year that the MINI Cooper was reintroduced, having originally been discontinued 20 years previously in 1970. This is one of the first of these iconic models.

Background

One of very few genuinely ground-breaking cars ever built, the Alec Issigonis-designed MINI is rightly praised for its innovative engineering, handsome looks, surprisingly spacious interior, and giant-killing handling.

These attributes allowed it to provide transport for millions of families who might not otherwise have been able to afford to run a modern car, and in competition it slew all who were daft enough to compete against it. It won praise from private owners, professional rally drivers, vanquished competitors, pundits, and spectators, all of whom keep it close to their heart, even now, more than 65 years after it first came into being.

Introduced in 1959 as cheap, stripped-to-the-bones family transport to beat the oil crisis, it started life with an 850cc engine fitted transversely with the gearbox squeezed into the engine’s sump. Front-wheel-drive, the MINI’s original rubber cone suspension freed up yet more interior space – and endowed the diminutive British car with unholy roadholding and handling.
And this was the real reason for the MINI Cooper’s success at the hands of folk like Paddy Hopkirk: most corners could be taken completely flat, something generations of learner drivers discovered to their glee…

Originally marketed as the Austin Seven and Morris Mini Minor, it was given the MINI moniker in 1969. It evolved in true Darwinian fashion over the years mechanically too, gaining engine capacity and performance at an almost exponential rate.

It lost its rubber cone suspension in 1964 in favour of a very clever Hydrolastic arrangement; this change improved the ride a little – the somewhat bouncy ride had been one of the original car’s few weak points – while retaining its prodigious grip.

However, no matter what engine was fitted, whether the original 850cc unit or the later 1275cc, the power and torque outputs were always relatively – and deliberately – modest. But then the engine only had only to haul 686kgs, which means that the MINI is surprisingly quick, both in acceleration and braking. Cheap to run too, whether in fuel, insurance, or maintenance and repair.

Still much sought after, a whole new generation of collectors and enthusiasts is flocking to the mighty MINI – and it’s the Cooper variants that will always have the biggest draw. In an age when bloated and depreciation-prone SUVs clog our roads, a MINI Cooper is a breath of fresh air.

The first MINI Cooper debuted in 1961, fitted with a tuned 997cc engine delivering 55 bhp—considerably more than the standard MINI. Its improved handling, disc brakes, and nippy performance quickly caught attention on both the road and the track. A more powerful version, the Cooper S, followed in 1963 with even greater success. With engine sizes eventually growing to 1275cc, the Cooper S became a motorsport icon.

The MINI Cooper's motorsport legacy was cemented with three victories in the Monte Carlo Rally in 1964, 1965, and 1967 (with a controversial disqualification in 1966). These successes gave the MINI Cooper an image far grander than its small size suggested, and it became a symbol of 1960s British cool.

However, by the early 1970s, under British Leyland’s increasingly fragmented leadership, the MINI Cooper was quietly dropped from production in 1971. Performance versions of the MINI continued in other forms, but the Cooper name lay dormant.

The MINI Cooper was finally revived in 1990 through a collaboration between Rover and John Cooper’s company. Spurred by renewed public interest in the classic MINI, the new models retained the familiar shape but featured modernized components and performance tweaks. The 1990 relaunch re-established the Cooper as a sporty, characterful small car, laying the groundwork for its enduring legacy—even before BMW’s later reimagining.

Overview

When introduced in 1990, the Cooper RSP (Rover Special Products) was the first MINI to officially bear the Cooper badge for nearly 20 years. This car is listed on the RSP Register as number 932 of only 1050 built for this country. It’s been restored with British Motor Heritage panels and had a full engine rebuild around eight years ago, since when it’s covered about 4000 miles.

RSPs were finished in a special black and red livery, and this one was first registered on September 20th 1990.

This one has been cherished by its current owner and has had significant sums spent on it of late. The mileage recorded is very low, but the documents and early MoT history and tell a more realistic story of continued use over the years. 


 

Exterior

MINIs aren’t often finished in black, as it’s a colour that tends to highlight panel imperfections, but we’re happy to report that this Cooper RSP wears the hue very happily indeed. It looks smart, straight and the paint has a gloss that 1970s Coopers could only dream of.

It’s not perfect – there are several minor faults that we spotted: a paint crack and scratch on the nearside front wheel, and a few small stone chips to the front end and lower areas.

There’s also a small paint crack on the rear nearside wheel arch and some paint peel to the joining rail on the nearside rear wing. The paint is bubbling in areas behind the rear chrome bumper and another couple of faults in the finish on both of the offside wheel arches.

Other than that there are a few light scratches in places and a small touch up on the offside front wing. But the car presents very well overall and these minor problems could be pretty easily dealt with by an enthusiastic new owner.

The RSP alloy wheels (different to the later Coopers) are in excellent order and the overall impression is of a well-loved classic MINI.

Last year the front, floors, A posts and quarter panels were replaced with Heritage parts (there are invoices in the document file totalling around £10,000 from last year).

Interior

The interior is very tidy but there are the usual signs of wear as you would expect, most notably on the steering wheel and the seat bolsters. But there are no tears or obvious damage and overall the interior is in nice condition.

Getting in here you’re reminded of the Alec Issigonis’ genius – there barely feels like there’s any room left for the engine, you’re so close to the front of the car. And as for cup holders…

The red carpets are very clean and the door cards are sound. There are a some small marks on the padded section at the top of the dash.

The interior is very original looking, right down to the correct, period radio/cassette player.

Mechanical

The 1275cc A+ Series engine has been over-bored to 1310cc and also has a Swift Tune gas flowed cylinder head. Along with this there is a Kent camshaft, Omega pistons, Clubman straight cut gears and an uprated X pin differential.

The Exhaust is a free flowing Maniflow system and the car has uprated Hilo suspension, which is fully poly bushed. Grooved and drilled brake discs are clamped by EBC Greenstuff pads. The enthusiast owner tells us that in 2021 the car was rewired and refitted with the original stereo system.

History

​There’s a stack of old invoices with this MINI so please study the documentation section of this listing. Along with the recent large expenditure there are older bills going back many years, plus old MoT certificates and the original handbooks. 

The current enthusiast owner is selling the car as she is now over 80 years old so has reluctantly decided it’s time for the RSP to move to a new home. She says:

‘I bought the car a while ago, as throughout my driving life of over 60 years, I always had a MINI – MINI Cooper S, MINI Flame, MINI Black, MINI Mary Quant, and MINI Mayfair to name a few. I liked the fact that this specific RSP model was a reintroduction to those who loved the original MINI concept, and decided I wanted one as my last MINI experience.

‘I have restored the car using quite a few Heritage bodywork panels, as you can see from the invoices. The overall condition is good – not concourse but good.

‘There are no known faults – it drives well and is fast. It’s special as it’s number 932 of only 1050 built for this country. I don’t think there are many of those left – around 30 to 40 according to the RSP Register. The engine VIN plate is original.’

 

Summary

A rare chance to own a special edition MINI, and one that was designed to reignite interest in the Cooper concept, something it was very successful in. 

Now offered with no reserve so will sell from the very first bid; the additional performance tweaks and recent restoration work just make it even more tempting.
