Scotty, I saw a 2007 Rav4 3.5L 6 cylinder with 125,000 miles for $4500. Can you tell me some of the common problems associated with the 2007 model specifically and tell me if it is worth taking a look at.
The most common problem is excessive oil consumption but that is only for the 4 cylinders the V6 ones are pretty solid and that is also a good price.

Here is the owner complaint site but the engine problems are with the 4 cylinder those are irrelevant to you so I would consider buying it but make sure to have a mechanic check it out first.
This generation came out in leta 2005, so consider your pick is probably not fully perfected yet. If you are interested, test it and take it to a mechanic for inspection if you like it.
Good luck!
