I have the chance to pick up my brothers 95 Formula A4 with t-tops for $5600. I didnt know if I would want an auto since I am a manually tranny guy, but after diving it a few days it is actually really fun. Dont know if all auto's had the performance button option but this one does. As far as mods it has a edelbrock catback (sounds really good), adjustable fuel pressure regulator, elbow, and a walborro 255lph pump. Car has t-tops and is black (my favorite clor for these cars),anyway I am curious if it is a good price. Also it has 99,389 miles and two minor rips in the leather interior. Included is a set of 3.73's to replace the current 2.73's which I bought as a b-day present last year for him,lol. Car has always been babied and will have a fresh tune up before purchase. Can the auto handle a 75 shot along with a 2900 (can I actually do a 3k without any problems?) stall, the gears some DR's, and in a little bit a cc306 cam along with LT's? What would I be looking at 1/4 mile times before and after cam....also I am a mile high so it will be about a second slower.

I am debating because I have a 95 T-Brd lowered on 18's with a built driveline (built tranny,2800 stall, aluminum driveshaft, 3.73 pumpkin) and heavy engine mods including nitrous. I dont know if I would sell my baby or I plan on a Cobra engine and use my n20....also have a t-45 5 speed tranny as well to swap in. I think I would do the engine swap and the tranny later on and have a very quick (currently around 375 at the flywheel) daily and use the formula as a weekend car/punisher.

....Opinions?
