Don't want people to get curious with big pics? Almost makes me want to say "Why waste my time.........." If the seller is that lazy posting the ad, makes you wonder how good he/she is at taking care of vehicles?
I've found that most people that have these cars (at least in my neck of the woods) are older and not very good with technology. I've come across some very nice cars that were poorly represented with their craigslist/autotrader/ebay/whatever ad. Just recently I helped a friend buy a '95 roadmaster that I found on craigslist. There was a very brief description and only one photo that was taken inside a garage, you could only see part of the hood and fender. After talking to the seller about the car we went to check it out. It was in fantastic shape and we ended up driving it home that night.
