Tough one. If you exclude my current Zed then I guess the black Capri 2.8i I owned in the 80's, I kept that for almost 3 years.

Funny you should say the Capri, ive always aspired to own one, one day! Love the style of them and the body shape is one of the best in my opinion.
If Bodie & Doyle were around today - I think the Zed would be the pool car of choice for CI5
