Best thing you can do is choose a car you like, and buy the nicest one you can find.What if you'd overdosed on Dorset Turnips and liked a Morris Marina, like Sir Tig.....
I was 19 and it cost me fifty quid with 6 months MOT & tax.
It was a great car though and I used do a lovely drift in it around a hairpin bend deep in the lanes near here!
....and don't forget it was the desirable 1.8TC coupe version....so the ladies went weak at the knees. Wet with anticipation.

It had a black 'go faster' stripe down the bonnet as well!
