I find this discussion very entertaining as an owner of a BL 1500 Spitfire. I'm under no illusions, the thing rusts away in front of your eyes and has loads of weird quirks. It's 33 years old so is probably better built now than when it left the factory. But for me, this is the fascination - all of the cars mentioned here are cult cars (allegros, marinas, SD-1's etc) and the fact that they are so badly designed, awful to look at and dreadfully put together makes them interesting. A big part of our motoring heritage.
Driving a reliable, well built and designed car is boring.
And despite what my elder sibling may say, I'd love to have an SD-1 on my drive for this very reason....
