well, i don't know if looking at old mopars for sale while sitting in one's "underwear" is helpful. but i can say that i spend hours every day on the computer looking at scores of ads for muscle cars in general and old mopars in particular and this practice does give one a great deal of knowledge about where the market is on these cars and where it might be going. if nothing else, looking at lots of cars listed in ads on line reveals how one car that is very nice and only listed at say $25,000 compares to a very "unrealistic seller" who has listed his car that isn't as nice for $35,000. it also helps to watch a lot of TV - especially the car auctions.
