I am looking at a 05 LQ9 with I am told only has 2500 miles on it. It has all of the accessories, PCM, and wiring harness. They want $3500 for it. Is this a good deal or does anyone think that I can do better. I live in the Houston area and I know that there is a good supply of these engines out there, but most of them have a lot more miles on them. Anybodys would be appreciated.
