G37s coupe 2008 90k miles

Define "a lot of money." In three years, with that many more miles on that car, I can't imagine it'd be worth more than $4500 or so. What condition is the car currently in? If it's been overhauled and you don't anticipate needing many big replacements, then that's one thing. The further depreciation plus major overhauls/repairs is an entirely different...

What's NADA, Kelly Blue Book, or whatever Canadian equivalent says about it?

Either way, the older it gets, the more miles you put on, it will always lose value.

Any maintenance done? W/that many miles, wonder if the water pump was done. That's big $$$ on these cars.

Wow that seems a bit high for an 08.
