1996 GM 323xxx miles, how much $?
 

So im looking for a used car and stumbled upon a GM with insanely high miles but the car looks to be in really nice shape, i have yet to test drive it but the ad says its runs very well with new tires, new battery and a fresh tune up. Obviously its a crap shoot with used cars but what would you guys be willing to pay for this ride, its just going to be used as a back up car:

I own a 99 lincoln continental with 200k miles and the only major work ive had done is a computer and ignition coils, does the 96 GM have anything i should look out for?

Thanks.

Yes check valve cover gaskets for oil leaks notorious for these cars

Looks like a nice car. Decent price for a dealer. Offer a little less. $850. I would check the following. Has the intake manifold been replaced ? Rust issues at the left front behind the wheel or in any other areas. How does the oil and transmission fluid look ? Check suspension and steering. Any questions, have a good shop look at it.
If you buy it, never allow the oil to go down from full. 4.6s don't like that.
