And they can't be purchased separately.
The BMW M3 coupe and convertible are no more, replaced by the M4. If BMW hadn't gone through with the number change, then today we'd simply have the next gen M3 coupe and convertible. But no, BMW opted to split the two and four door variants into two models. Many M-brand enthusiasts aren't at all happy by the move, but what's done is done. So perhaps as a way to commemorate the discontinued M3 convertible, someone is now selling a pair of them on eBay: a 1991 E30 M3 and a 2013 E92 M3.
Both convertibles. Both special. Why? One represents the first generation and the other the last. The E30 is a fully documented, two owner car with less than 75,000 miles on the clock. Just 786 E30 M3 convertibles were made. Power, of course, comes from a 2.5-liter inline-four with around 240 hp, and paired to a five-speed manual. The E92 comes with that wonderful naturally aspirated 4.0-litre V8 with 414 hp. It's paired to the familiar dual-clutch gearbox. It has less than 10,000 miles and there's still time remaining on the BMW warranty. But if you want one, you'll have to buy both. The seller has made clear this is a package deal and the cars won't be sold separately. The current asking price is $110,000 for the pair.
