All your automotive pricing guides are based on historical transaction prices. NADA for example compiles both wholesale (auction) and Retail transaction prices (from dealers). The only consistant item with prevost evaluations is the shell and the variable becomes the converter. I don't know of anyone consistently compiling and analyzing high line bus transactions. The numbers are so limited and the difference between converters and installed assessories is so wide that anyone attempting to create a price guide especially in this business atmosphere is nothing more than a "gut" feeling. I think some owners are "firesaleing" coaches to raise cash, a sale like that doesn't really represent the true value of the coach. So until someone has access to accurate info its best to do nothing and let the marketplace dictate prices.
