Engine parts will be ok... as long as you can get them from mercedes. Body parts may be difficult but unless your bumper is completely destroyed, a good body shop can at least repair it. It may not look the best but it is possible. I am sure in about 10 years someone will have the parts or make the parts. Look at Delorean. Probably about 9 or 10 thousand cars were made and still about 8 thousand left in existence. You can still get body panels. As long as there is a cult following, things will work out. I would say our cars have a cult following.

People were tailgating me this morning. A friend has a really mint Delorean (fully restored) and people tail gate him get angry and speed around him in a no passing zone. It doesn't matter if you drive a Ferarri or Lambo... people would still be tailgating. The bumper cost more than their car. Still no respect for anything on the road today.
