If it's a cable tranny then it's from a 4th gen, not a 6th gen. The 5th gens on up all have hydro trannys. You should test drive it and then determine if having a cable tranny is bad or not. Some people prefer it over hydro, some prefer the hydro; all a matter of opinion. If the car is in good condition (no rust, major dents or damage, drives and turns good, not leaking fluids, etc); then that price sounds reasonable. But when you buy a car that already has an engine swap and modifications, you never know if they were done correctly or if the person beat on the car every day.
Edit: damn Ace, looks like I'm jsut 1 step behind you on here
