the wierdest idea to do to a sub compact

i have a ford aspire and i was wondering about mods to make it look cooler

Get a really hot blonde and strap her in the passenger seat.

a lot of the stuff you're going to have to do will be custom fabrication. For ideas check out fordfestiva.com They have a club called fast festiva aspire street trends. They also have pics of decked cars, and concepts, and just general help on your specific car.
Good luck, and don't be ashamed of your festiva. There's a 13.2second geo in cali that owns all corvettes on the strip (obviously not on road courses.. there's a 40k difference there) So know that anything's possible.
