A few question about 87 tubro supras

[BOOST87]

HI all.. I'm new on this board.. I have not bought the car yet but i have put a deposit down.. I have a few questions regards to the car.. The guy wants 3k for a 1987 supra turbo with 89k miles on it.. Car had water pump, timing belt. and headgasket replace wtih 2.0mm hks gasket not too long ago.. This car is an automatic.. Since i don't have any prior experience to this car i was hoping someone can show me some things to check.. I did the regular check up such as smoke coming from the pipe and all that regular stuff.. I have a few q's of my own.. First of all.. i check the weight of the car and it said 4460 lbs. on the driver door.. WTH !! is this right?? holyshit..Car is really heavy... SEcondly what are the shift points on these cars.. I notice its very high shift points.. Can someone tell me what the shift points are for 1st - 2nd, 2nd - 3rd, 3rd - 4th.. I want to see if it matches how the car respond when i test drove it..Also..I don't know if the reverse on the car is going or not.. Either that or the car is heavy and it takes a little bit of gas to reverse it.. Any recalls on this car? Defects besides headgasket? Car has basic bolt on such as greddy sp exhaust, upper ic with turbo sx bov, intake.. I think that's about it.. Oh and what is stock boost on this car? What is normal and what is pushing the boost level on stock turbo in this car? Oh yea.. can someone estimate what a rebuilt tranny would cost on these cars? Just in case i mean..That would really help alot..and anything else you can think of would be great..
Oh one more thing.. The car has a 7mgte 3.0 turbo block .. i'm located in NYC
