i always get a kick out of looking for a car that i know more about than the owner, the best was when a guy told me that a 91 pickup has full time 4wd and a locking diff. i drove it and he said put it in 4wd when i turned on CONCRETE he said you hear that grinding clunking noise "thats the locker kicking in....well i taught that guy a valuable lesson that day. a week later he listed the transfer case being defective...haha...another truck i looked at had a horrible missfire, the guy said he coouldnt figure it out and i knew the problem the whole time as soon as i looked at it i offered him 600 bucks fixed the misrouted vacuum line and drove it home on a 200 mile trip, then that was my 5 speed swap donor!
