Looked at an 08 D7 155 today. Don't know much about these sleds so I need some help. The sled is in pretty good shape, just real dirty from sitting all summer. It has 5000 miles on the chasis and SUPPOSEDLY less than 1000 on new crate motor and track. Motor is totally stock. Unfortunately he has no paperwork on the motor because the prevoius owner had it done. It started after about 4 pulls - stone cold (he said it hadn't been run since last May), sounded ok to me. He's asking $3K for it. Is this a good possibility or should I stay away from it? The only mods are bar riser, lefty, and airbox - it's also geared down a bit.
