I still have my Triumph Stag that I even went out in the field min in, whenever anyone would accuse me of having a car that was maybe a bit too flash, I would offer to show them the logbook where the previous keeper is shown as being the London Bethel.
The most fun car I ever owned was a ratty Triumph Vitesse, (they look like the little old Triumph Herald), except somebody had put a 3.1 Litre V6 Ford Essex "X pack" engine in it with a hot cam and rather large carb.
Once I had started the car rolling, I could then hit the throttle and nothing would match its acceleration, I couldnt give it when pulling away as the diff used to explode.
It was the fact it looked like an old dads car yet would match the latest Mercedes Sports Coupes was what I most enjoyed, I followed an Audi TT100 down the A22 once, whatever he tried to do, I was still right behind him with an indicated 125mph, you can imagine what that must have looked like to the cars we passed, an Audi travelling at 115 with what looked like a Triumph Herald trying to get past!
