My aunt has a 2009 Jeep Commander that she wants to get rid of to get something smaller. She has proposed a straight up swap for my wife's '10 Rav4 (one payment left).

On the surface this looks like a good deal to me, the Commander seems to be a substantially larger vehicle and has lots of options like rear A/C, heated seats, etc.

I'd be very happy to get rid of the Rav since I've never liked it, but I don't know anything about the Jeep reliability wise. Would it be more trouble than it's worth? Aunt says it has around 35K miles and has never had a problem of any kind.
