2003 3.0i fast road/trackday car - £4800

The time has come to upgrade to a 35i to build as a Ringtool, so my much-cherished E85 needs to go to a good home.

For Sale: Mechanically perfect, money-no-object maintained 2003 BMW Z4 3.0i manual. £4,800 (plate not included). Car can be viewed in Norfolk or London.

I’ve owned this car for 2 years after buying from another enthusiast owner, and have made the decision to sell to upgrade to a more focused track car.

Over the past 2.5 years, every single common issue has been resolved (with receipts) and around £3000 has been spent on upgrades (with receipts) to make it go, handle and stop much better than the standard car. I’ve used it on track and on multiple trips to the Nurburgring, and it would make an excellent fast-road/track car without compromise. It’s completed a 2000 mile Eurotrip and a two-day Nurburgring trackday without a single issue since I’ve owned it.

If you’re looking for a Z4 that can be enjoyed properly straight out of the box without any modification, and without any worries about common issues, this is the car for you. I suspect there’s probably not another Z4 for sale with such a comprehensive recent history of work. The beauty of this car is that you get the mechanical bits from an E46 wrapped up in the lighter body of a two-seat convertible. At less than half the price of an equivalent S2000, it’s a bargain too.

Had a nice man come and clean the car today, because I thought it deserved some better photos.

No idea why the camera has made the driver's carpet look so bad. Perhaps over-exposure, as the photo looks quite light? Either way, it's barely noticeable in person.

The seats look superb

Does the diff make a big difference?
All credit goes to Usel for the seats. If you could be bothered to wade through the pages of drivel on my thread, you'd see that I was on the verge of selling because I hated the Sport seats so much. The E89 seats are a complete gamechanger if you're taller or wider. I did the drive to the Ring and back plus 40 laps over two days, and had no aches or pains. They are a big part of the reason I'm looking at an E89.

On the diff, I'd say it was the best modification I've done, slightly ahead of the coilovers. I found the standard car sluggish and not keen to rev (consistent with my previous M54s), and going for the 3.64 feels like I've liberated a bunch of power and lightened the flywheel. It revs so much more keenly, it pulls harder, and the dropoff between upshifts is so much smaller. Everyone with a 3.0i should do it.
 
The paintwork isn't mint, because the car is 21 years old and I'm not particularly obsessive about that sort of thing. But it does bead very nicely, thanks to Autoglym ceramic wax.

Looks fantastic and very keenly priced considering all of the work involved!
Thanks kindly.

Have a chap coming to see it this weekend, with a view to taking it away if he's happy.

I'm going to need to be patient on my next purchase, I suspect. The Z4 35i is rare enough in decent condition, but I'm looking for a car that's already had some of the bits I'm planning to do fitted and that's making it into a bit of a unicorn hunt.

I'm trying my hardest not to just buy an M4 convertible, but it's not easy to resist something that works so well out of the box.
