This car was brought over from Germany and did not have a vin # when purchased. I had to obtain one here from the Highway Patrol. The car thinks it is an AMG--has the badges on body and engine, has way more suspension than the regular 95 e320 Cabriolet, has wider fender wells and is faster. Hoping for the best, I purchased a set of monoblock AMG wheels from tire rack. They are the same size of the old wheels, but now the speedo is off by 7 miles per hour. Anyone know if it is possible to recalibrate the speedo on this car?
