how can i run a vin number for a car befor i buy it

Try going to Carfax.

CARFAX CARFAX CARFAX, SO worth the 50 or so bucks, also is it a private seller, or car lot - dealership, professionals are used to potential buyers having the car taken to be inspected BY THAT CARS DEALERSHIP, or any second opinion..if the seller is non-willing either you are not worth their time and hassle, or they are hiding something...often cars that seem cheap are from auctions, and although noone can predict future issues, some are more likely to have them....may i ask the price, 97 maxima gxe, and geographically, (new england, florida)....
