i dont know what to do

OK i own a 97 accord but i want to trade it in for a nw car. it has 93000miles on it though. there are 2 cars that i am really looking for, a 97-99 maxima or a 95 to 99 240sx. i found a 240sx and the guy told me that he could make an even trade and gice me 800 to 1500 back. but the catch is that the car has 130,000 miles on it. but i really want that car. i figured that i could save some money and add it to the 800-1500 adn get the sr20DET but first off i wouldnt know whre to begin and i have know idea who could instal it without messing it up. what should i do. and if you have any other suggestions that are completely off the subject of the 240sx please tell me.

You will probably get better answer in the Nissan forum's. If your thinking performance, go with a rear wheel drive car.
