I am in the market for a 05 G55 with around 25k-35k miles on it. What should i be paying for a truck like this and does anyone have any leads? Is there anything that should be cautious about when buying one? Any major problems with the 05's?

How do these trucks hold up and and what kind of mileage(longevity) do you plan to get out one? I figure I'll probably keep this thing a while, 3-4 years or so.

Also how do the warranties work on these things and what do you recommend?

Thanks in advance!!
