But it was - and keyed-up by huge demand from buyers, BMW decided to rush the Z1 into production. Today it's most notable for its doors, which drop into the sills. But the Z1 was a sweet-driving car, balanced and not over-burdened with power. The Z1 also bristled with advanced design features and weight-saving touches.

Initial demand was strong, with BMW receiving orders for 3,500 vehicles before production began. However, demand dropped significantly around 1988 and BMW ended production in 1991. There is speculation that the drop in demand was due to the early inflated demand from speculative investors.

The numbers game also reveals a bit more about the Z1, too. BMW built 8000 examples and, of those, just 150 were made for the UK market and featured mph speedos. And this car, according to the record, is build number 148 of those 8000.
