Your on the right track
I forgot about volkwagons. That's my pick. Any volkwagon enthusiast will tell you to go with the 1.6L Turbo. There is a huge aftermarket for them. You could eaisly get a Gti into the 13's or lower. I got smoked by one last year in my turbo civic. He ran low 12's with a upgraded turbo, exhaust, fuel mods, and a tune.
Plus VW has them new funny ass commercials so thats a plus
