1997 Mercedes-Benz S320 Reviews

Overall I am impressed with the total package.The fit and finish as well as performance and fuel mileage is very good. That inline six (104) really shows it's muscle with a heavy car such as this. Plenty of leg and head room too!(but that radio "code" thing has to go!!)
