So I found a 99 sr5 with 136k miles, one owner, crystal carfax, no rear diff lock. This thing is tits, not a scratch on it, interior is perfect. Problem is, the dealer tells me "I changed the timing belt, water pump, and all the accessory belts, and put new brakes on it. I do it on all the 4runners I sell." He's got like 5 on his lot currently. But of course uses "his mechanic" so no paperwork. He wants 9k for it, down from 10 (in the PNW). My heart wants it, other parts of me say no. There are a lot of expensive nasty looking 3rd gen 4runners around here, this one is by far the nicest I've seen out of a dozen. WTF do I do?
