I came very close on a couple of occasions to buying an E28 M5. They are perhaps the zenith of 80s BMWness, and the magic of depreciation means you can get a very nice one for less than a new Kia. But at the end of the day these cars combine supercar maintenance regimes and costs with middling performance by today's standards meant that I couldn't justify it. Maybe someday.

As an aside, whenever anyone starts moaning and bitching about how BMW's M division has lost the plot because it is no longer building cars as pure and as focused as the E30 M3, the E28 M5 is the car that I flash to. Both before the E30 M3 and after, the M division was about putting very high performance engines into luxury sports sedans, not about building homologation specials. The E28 M5 stands as a perfect example of this, and has just as much claim to M history as does its more talked about smaller brother.
