.........grey Jap. and Euro. imported cars situation of parts availability and maintenance-fixings as per currently:-
- Japanese luxury cars such as NS skyline, TT alphard and etc. may facing long waiting whenever place a special order parts
would take 30-90 days. OBD reading electronics fault codes may available at some of major grey distributors to assist
to solve off the engine and transmission problems for thier customers but on fixing cost of labor(labour) gonna be higher
than general standard Japanese cars.
- European luxury(as per you mention on W 211) and those supercars, you better to be sure that both of parts availibility,
OBD read-out and fixing costs are would be outstanding as you might guess it by yourself!!
- Please do make your own conclusion
