It would be Old Speed as my 59 is bound to be. A hot 30 horse engine, supercharged. Wide 5 sprintstars with 4 equal tires with rougher profile tires. Not lowered at all or maybe just a little in front. Old color like Mango Green or maybe the original to my car Kalahari Beige. Bucket seats lots of meters and a 3spoke standard steering wheel. Porsche style quickfill gastank. Leather straps to keep the bonnets closed. A lot like the Swedish hillclimber that I saw at Bad Camberg two years ago. You know, the grey one with the bubbles on the engine lid.
So either that or I would lower my car a lot in the front, run skinny tires in the front, fat rubber in the rear, put on lightweight mag wheels. Dechrome the car and spray it some bright catchy colour, top it of with some ali T's instead of bumpers. Fit a spartan but classy interior with some meters to read what is happening in the back end department where I would be running with a hot engine with two big carbs. Fumes would be exiting at both sides of the car out of two big mufflers. Man, it would have to be fast enough to shake some american muscle on the strip. My car would not be in a particular style but at least it would look cool.
