We've all done things to cars and regretted it after, sometimes straight after sometimes 10 years later when you think back.
I think mine would be when i 'Customised' a Hillman super minx just for a Hemsby rockabilly weekender. It was green so me and a mate put pink scallops up it, pink wheels with painted whitewalls and then (this was classic) we masked the green seats up and painted pink stripes down them for that 'tuck n roll' effect. It actualy looked ok for a 1 day and £20 custom job but when you sat in it you emerged with pink stripes up your clothes!
The year me and fly met mitch, at Hemsby weekender, fly had an HA viva van with scollops on and `beaver patrol` on the back, also had the grill that now smiles on my dead victor....
actually that grill has been on a few vauxhalls, cos it started life on that severely chopped F type that Fly had `The phoenix`.
