In terms of speed, and I mean quick manuals, what company, and model, do you prefer? I ask because I am big on speed, and I know a few quick cars. Like the 1993 Mustang 5.0 v8 is good. What other cars are fast, but I could find on craigslist for a nice price. Budget: 4000 and under. What cars are also very easy to alter the engine with? I know civics are pretty good to mod.
