BMW's Z1 was expensive when new and is rare today. Unusual looks and very cool sliding doors make it a winner today
The Z1 was initially a concept at the 1987 Frankfurt Motor Show, but buyers were soon clamouring to buy one, leaving BMW to rush to get the innovative little roadster into production. Most notable for its doors, which drop into the sills, the Z1 bristled with advanced design features and weight-saving touches. Powered by the same engine as the 325i, it was no ball of fire considering its high price. Rapidly diminishing interest from buyers saw BMW halt production after 8000 were built. Only 50 official UK imports, but many more have been shipped in. Plastic body doesn't rust, but it can crack so check carefully. Values continue to climb steadily.
