83k on a 2002? Mine's only got 102k. Oh, wait...

Aside from that, if it's a 4x2, offer $9k max. If she balks, tell her its a manual and you'd really prefer an auto (even if you don't). 5 speeds usually pull down less than autos.

If it's a 4x4, up your offer to $10k max.

All of the above is predicated on the hope that the warranty:

1. Is transferable (usually a small fee involved), and,

2. Will cover the rear main seal leak.

Other things to check:

1. The level of coolant in the overflow. If it is bone dry, act really worried and drop a few hundred off the price again.

2. Steering box for wetness. If so, find out if the warranty will cover replacement steering box ($1500 to $1800 part, not to mention labor).

Yes, you are only 22k miles out from the timing belt change ($700 or so).

Finally, ask yourself if you're willing to jump into a vehicle that gets 14-17 mpg in town and 16-20 mpg on the highway and that you may be hard pressed to sell when you can't afford $4.50/gallon gas later this year (nobody will want to buy it from you).

Edited to add: Depending on what side of the country your on, I might know someone with a 4x4 auto with 102k miles on it that will give you a swingin' deal...
