Why carfax history reports don't always work

I haven't posted to this blog in a long time, but I will be adding stuff regularly. The wholesale car market for premium cars is still on fire. It's nearly December and prices still look like they did in may and june on most cars. There is a real shortage of good cars out there. That's no b.s. The shortage is for real. I buy mainly BMW, Mercedes, jaguar, land rover, Audi, vw, And Porsche product. While it's true that there is not a really bad shortage of these used cars in general, there is a very big shortage of these cars that are actually in excellent condition. People who are not in the car business usually say "don't all Mercedes owners take care of their car?". The answer is absolutely not. At least half of the used cars out there have had some sort of paintwork, bodywork, dents, dings, been smoked in, etc. These are cars that I think are less than excellent condition. Most of these issues will never show up on an auto check report or car fax report. These shaky cars ar bought by dealers and sold to consumers everyday and they're advertised as great cars with no stories because the carfax is clean. For all of you highlinecar buyers out there, do yourself a favor and get the car that you're looking at checked out by an independent mechanic. Even the so called "certified" cars have previous paintwork and bodywork. Buyer beware
