I have a 2000 ML320 with the M1 option package listed on the warranty history sheet. I have seen on other forums that the M1 option included a trip computer in the overhead console and a lockbox under the passenger front seat. My vehicle has neither but does have the compliment of other features listed in the M1 package. I bought the vehicle used. Is it possible the original owner opted to exclude some of the M1 options

Thanks,
