2006 BMW 320Si

One of a reported 122 left registered on the road out of 140 survivors from the original 500 sold in the UK (information from howmanyleft.com), this lovely low-mileage 320si comes to the market from a three-year ownership. The vendor has enjoyed this desirable and rare BMW.

The BMW comes with all the original owner's manuals and an excellent service history. The most recent service was carried out in November 2024, since which it has covered just 30 miles. It is also worth noting that the timing chain and tensioners were replaced in January 2022.

For anyone looking for a desirable and collectible BMW, the 320si is the perfect choice. With all the extra touches over the standard 320, the 320si stands out from the rest, and with just 140 left registered in the UK, it is certainly something you don’t see every day.

Walking around the 320si, there don’t appear to be any dings or dents, and the panel gaps look to be equal. With a choice of just three colours for this special edition - Carbon Black Metallic, Le Mans Blue, and Carbon Schwartz - this example is finished in the striking Le Mans Blue.

Starting at the front of the car, the M-Sport bumper is in good shape with no scuffs or damage. The fog lights and headlights are also in good condition, with no splits or cracks to the lenses. There are some minor age-related stone chips on the headlights, but these could probably be reduced using one of the headlight restoration kits available. The bonnet has some stone chips across the front in keeping with the mileage.

Along both sides, the swage lines match across the doors on both sides. All of the windows appear in good condition, with no noticeable scratches, and the window seals and trims look well maintained.

At the rear, the colour section of the bumper is in good condition with no scuffs; however, there is a small scuff on the centre grey section, which could possibly be reduced with a machine polish. The light lenses are in good order, with no splits or cracks.

Being the si model, it was only right to fit it with the 18-inch motorsport wheels, which are slightly wider than standard wheels. There is a small amount of corrosion to the faces and some minor kerb damage, but nothing that couldn’t be easily rectified with your local wheel refurbisher.

Inside, the BMW is finished in leather with some nice aluminium inlays on the dashboard and centre console. The leather seats are in good condition, with just a minor amount of colour wear on the driver’s bolster. The passenger and rear seats are in good condition, though we did notice a small 1-inch scratch in the centre of the rear seat. Each of the door cards appears to be free from scuffs or damage.

The dashboard is free from damage, and the instruments are working correctly, with no warning lights displayed when the engine is running. The odometer shows a reading of 65,223 miles. All of the switchgear looks in good order and is reported to work as it should, and the car has retained the factory BMW Professional CD head unit. The leather M-Sport steering wheel and ‘golf ball’ style gear knob, unique to the si, are in good condition, with no real signs of excessive wear.

Throughout the cabin, the carpets are in good order, and a set of fitted mats is installed to help protect them. Inside the boot, it is clean and tidy, and the original BMW First Aid kit is in place.

With a reworked engine, the 320si’s 2.0-litre unit was set to deliver 171bhp and 150lb-ft of torque at 7,000rpm, capable of reaching 0-60mph in just 8.1 seconds.

The engine fires up without hesitation and has no untoward noises. As mentioned earlier, the car had the timing chain and tensioners replaced in 2022, giving peace of mind to the new keeper. Inside the bay, it is well presented, with the WTCC decal in place on the air intake and, of course, that super cool carbon fibre rocker cover - another si edition feature that helps reduce weight. Fitted with a six-speed manual gearbox, the gear change is precise, and the car pulls strongly through the gears, delivering an engaging driving experience.

From the factory, the BMW has M-Sport suspension, which sits slightly lower than standard and provides a firmer ride without being harsh. There are no knocks or bangs reported from under the car, and the brakes are said to bring the 320si to a stop in a straight line.

Looking at the underside, this presents well with just a small amount of surface corrosion on the suspension components. All of the plastic panels appear in good order, with no splits or cracks spotted.

With all of the owner's manuals intact, anyone who knows about these cars will know that regular servicing is key. Fear not—this car has a well-stamped service book, including several invoices to back up the history, showing the BMW appears to have been well maintained over its 65,000 miles.

As mentioned earlier—and it doesn’t hurt to mention again, as it’s a big job out of the way—the timing chain and tensioners were replaced in early 2022, and a recent service was carried out just 30 miles ago.

There is a current MoT on the car, valid until 28th November 2025.

For the budding touring car driver—or, in fact, just a petrolhead enthusiast who wants something a bit more desirable than your average M-Sport BMW—the 320si presents a superb opportunity to stand out from the crowd in a subtle way.

Become one of just 120 owners with a 320si actually registered and on the road. With relatively low mileage for its age and a well-stamped service book, this BMW is perfect for any enthusiast, and with a recent service, it is ready to be enjoyed.

We estimate that this 1-of-500 UK BMW 320si will fetch in the region of £4,000 - £7,000, which, let’s be honest, for something with such a low number in circulation, is quite a bargain.
