I wouldn't worry about it. Since he is your friend, I'm sure he will let you test drive it without him being in it. Take it on the highway and do a WOT (wide open throttle, in other words pedal to the medal) and see if you notice anything unusual. Then while doing around 55-60, do another WOT and see if it down shifts correctly.
The around town, see if you notice it doing anything out of the norm. If not I would say its still good. With how you describe him taking care of it, I wouldnt think twice after I did my tests.
In very good condition with the mileage, they are going for 8,000. So
The price is right so I would say go for it.
What are the options? I would need to know for a near exact price, like if it is 4WD, Navi, etc.
Keep in mind this is around Atlanta, so the price could be a little different around our area but it's mostly the same in most areas.
