Offensive to sellers but have people gone over the cliff on Car values

Price always always always comes down to the buyer. The seller will only need to say yes at a number. The buyer has to push the cash over. Personally the last 3 cars I've gone to look at, that looking at the pictures looked like reasonable value for the price, I walked away from. Pictures made them look great, and the sellers had little idea what they really had. By that I mean rust that was "repaired" (cough), and previous painting and bodywork coming through, and mechanical shortcomings that I honestly felt in each case the seller was ignorant of. Some I mentioned as part of say no, some I didn't want to hurt feelings knowing I'd never see the guy again.
I think the market is a combination of a few things: stocks are doing well along with the economy for most people, the hyperfocusing on auction type pricing, and the ever-shrinking pool of potential buyers all effect the market reality. Personally I see the pricing coming down, except for rare or super desirable models that still have originality, or are correctly (and completely) restored.
