so i found a low mileage (45000 mi) 04 E55 that I am looking at. I am going to have my MB Mechanic do a thorough inspection on the car, but I was wondering if anyone here can give me any quick tips to look at the would tell me if I should walk away or not. It is about 100 miles away, the owner said he will bring it up to my Mechanic if I put down a substantial deposit and pay for all of his expenses.

Thanks,
