IMO don’t do it unless you have a good budget for maintenance or the car has a Starmark warranty. And extend the warranty as far out as MB will let you. If used only once for a significant part, it will pay for itself many, many, many times over. And definitely research the S class on this board. Fine car. Only downside is the expense of maintenance. Also, if the car is Starmarked, you won't have to have it inspected.....
