I have an 01' Monte with the stock 16s. Looking to keep it stock so I'd like to purchase my buddy's 17" Diamond-Cut OEM Chromes off his 04' Impala. The wheels have about 30k miles on them. What do you think is a fair price to pay for them?

 

Isn't this a factor of condition rather than "Miles on them"? They go for about 2-Bills a wheel in the aftermarket. Some, more than that. Without actually seeing what is is you're getting ready to buy ... any assignment of value to them would be arbitrary and nothing more than a guess.

Your guess is as good as ours!

 

IMO, $125-150 for a used wheel. I'd say $500-550 for the set, myself. For $800, you can get new aftermarket wheels.
