if you are talking about CPO, there is way more than 150 points to inspect.
CPO price is different from vehicle to vehicle. reason I say this is cause if tires fail on one car and pass on the other of course the car that needed tires will cost more to CPO than the one without tires. I have CPO'd cars that need nothing but an alignment which is part of the CPO process. then I have done 15 hrs worth of work on some CPO's. CPO base price is pretty much equal across the board. MB has guidelines for dealers to follow, but they don't always follow them.
