1993 Nissan Maxima SE

Ok I found this car and if I get a chance (will find out soon, within 1-2 days) I'll most likely get it.
The things that I found wrong while test driving it was the power locks button and the driverside auto power button didn't work, and A/C wasn't working.
And it sounded like a belt was loose and somewhat lack of power, maybe it's just me though.

Comment: 4 door, V6, 3.0 litre, 24 valve, 190 Hp, auto., A/C, fully loaded, power glass sunroof, power seat, air bags, alloy wheels, AM/FM cassette, black over black leather. Good km. Call for more details. $6488. GTA AUTO (416)661-0800 (CBYXWL)



Is that a good price for it? Canadian price remember.
What are the positives/negatives of the car?
Any bad things that might go wrong, as in tranny usually has issues or etc. Basically tell me everything you know
thanks
