ive searched the internet and googled it and i cant seem to find a intercooler for my car. can anyone help. and i also need help finding a good benz mechanic because i know everyone and their mom hates to work on this car.

Intercoolers were not available for your car from the factory, but some people have made their own custom adaptations.

As for a mechanic, you might want to ask on the diesel list and state your area.
