Highlights


  • Rare Baur convertible model
  • 2.5-litre engine from an E30
  • 5-speed manual transmission
  • Comprehensive service history
  • MOT to November 2023

The Appeal


Long before the first ‘in-house’ 3-series convertible was launched (which was the E30), Karosserie Baur, the Stuttgart based coachbuilders, built 4,595 “Top Cabriolet” models based on the E21. In reality, it’s more of a Targa than a full convertible, but that doesn’t detract from both its rarity and its ability to give that “million miles of sky” feeling to the driver.

This example has been owned by enthusiasts and collectors for the last 23 years and benefits from some tasteful and well-executed enhancements that make it a much more engaging and usable car. Complete with a fine service history and maintenance record, it makes this charming and quirky machine quite the thing. If you’ve always wanted a show-stopping modern classic, this has to be on your list.

The Interior


  • Black leather Recaro sports seats
  • Rare ‘fishnet’ headrests and leather trimmed wheel
  • Modern Sony stereo system
  • Electric windows and door mirrors

Overall, the interior of this Baur is very well maintained. The black leather of the Recaro seats is in good condition for the vehicle’s age, with just a little creasing and wear evident on the seat squabs and bolsters, but nothing that would concern us. Of particular note are the ‘fishnet’ style headrests, which are quite rare. The original headrests also come with the car.

Complementing the leather, the black vinyl door cards also present well, with no signs of damage or notable wear, just a few minor blemishes as you’d expect.

Smart red carpet runs through the cabin, twinned with black overmats which have complementary red binding to the edges. In general, all the carpeting looks to be in very good order, with just a small area where it appears to require refitting to the driver’s side.

As far as we can see, all of the trim, driving controls and instruments look to be in fine fettle. There are a few marks and scuffs to some of the interior plastics, as befits the age and mileage of the car. However, overall it all looks to be in excellent condition with no notable damage or wear and no cracks to the dashboard. We particularly like the leather-trimmed, sporty 3-spoke steering wheel. A modern Sony CD/radio head unit has also been installed, and this features both USB and Aux ports.

At the back, the boot is in excellent condition, lifting the carpets shows the floor to be solid, with absolutely no evidence of corrosion or repair that we could see. It’s trimmed with black carpet and also holds a spare wheel and toolkit. When the roof panel is removed, this also stows neatly into the boot space.

The Exterior


  • Henna Red paintwork
  • Removable roof panel and drop-down rear section
  • Period correct BBS alloy wheels

Finished in the delightful shade of Henna Red, the paintwork appears to be in very good condition, with only a few minor blemishes and some areas of chipping that have obviously been touched in. There is also a little lacquer peel to the near-side B-pillar, but again it’s nothing severe and should be easily remedied.

All of the panels look to be neat and straight, with no signs of damage or serious corrosion we could see. There’s a small amount of bubbling to the bottom edges of the doors and the lip of the bonnet, but otherwise it all looks to be in very good order.

Much the same can be said of the trim: it shows well with some nice brightwork, clear light lenses and glass which appears to be free from chips and cracks. The headlamp wipers are currently non-functional. But the foam rubber boot spoiler looks to be free from cracking and UV damage, which is usually quite common on this vintage of BMW. The vendor has also fitted new door mirrors. 

Of course, the car’s key point of difference is the Baur engineered roof. The main panel lifts out to stow in the boot, while the section from the B-pillar back drops down in a traditional convertible way to ‘sit on’ the rear deck. There is a tonneau cover which neatens it up nicely when stowed. All of the roof’s elements look to be in good order, with no damage or fading from UV that we could discern. There is a tiny hole to one side of the tonneau, but it’s very minimal.

The original alloys would have been smaller metric items, which are very expensive to keep shod with tyres. Therefore, they have been switched out for larger, period correct imperial BBS items. These 15-inch alloys suit the car perfectly and look to have been kept in excellent condition. They’re shod in a matched set of nearly-new 195/55 Falken tyres.

Underneath the car looks to be clean and straight, with no evidence we could see of corrosion or damage.

The Mechanics


  • 2.5-litre inline-six engine from an E30
  • 5-speed manual conversion
  • Power steering

Originally supplied with the 2.3-litre automatic drivetrain, a previous owner has had a 2.5-litre engine from a low-mileage E30 fitted, alongside a manual 5-speed transmission. In such a light car, this should make for an engaging and powerful driving experience. 

The engine bay itself is very clean and tidy, with no signs of leaks or other issues. The installation looks to have been very neatly carried out and looks factory.

Other enhancements that have been carried out include: uprated Bilstein sports dampers, a Hartge front strut brace and stainless steel exhaust system.

We’re assured by the vendor that it offers a superb combination of performance and handling, with a beautiful inline-six growl. They also tell us that there are no leaks, smoke, untoward noises or mechanical issues they are aware of.

Summary


E21s are already becoming a very rare sight on our roads, but can you remember the last time you saw a Baur “Top Cabriolet” in the wild? We certainly can’t. It’s a properly rare groove machine and sure to attract plenty of attention, both on the road and at shows.

This example has been tastefully and sympathetically enhanced and modified to make it more practical and more fun to drive, while retaining that iconic BMW DNA. We think it’s a very desirable little car and would happily grace any collection you care to mention.

About Max Bids

The max bid process allows you to bid without any hassle.
Enter your maximum bid and we will then bid on your behalf to ensure you're the highest bidder - just enough to keep you in the lead and only up until your maximum.

Anti-sniping

C&C prevent auction snipers from bidding in the last seconds to win an auction.
Auctions are extended by 3-minutes if anyone bids within the last 2 minutes to allow other bidders to react and counter-bid.

Auto-bidding increments

  • If your maximum bid is equal to or below the reserve price, your maximum bid will be applied in full if you are the highest bidder.
  • If you are the highest bidder and place a maximum bid above the reserve, we will automatically put in the reserve as your first bid.
    • Once the reserve has been met, Car & Classic will make sure you are the highest bidder using only the bidding increments stated below.
    • We will keep you in the lead up until your maximum bid OR the increment closest to your maximum bid, providing your maximum bid is enough to cover the increment value.

Bid Amount Increment
£0 to £10,000 £100.00
£10,000 to £50,000 £250.00
£50,000 to £100,000 £500.00
£100,000+ £1000.00

Automatically outbid immediately

When you place a max bid and are outbid immediately that means that another bidder has placed a max bid limit which is higher than yours.
You can bid again and we will use our automatic bid system to try and get you as the highest bidder.

Matching max bids

When there are two max bids of the same value, the one placed first remains the lead bidder.

What are pre-bids?

A pre-bid means you’re able to place a bid before the official start of the auction.
You will be notified whether or not you are the highest bidder when the auction starts.

Problem with your bid

Bids are contractually binding. To help protect you, we have some rules in place if we think it's been mistyped. Please check and amend what you have entered.
