I actually like all the benz models for the most part. I do not have my heart set on a certain model.

I am concerned with tranmission failures (auto) on 300d and 240D that I have seen advertised, common problem with the older benzs? What should I look for in terms of maintenance on the transmission?

I am looking at a 240D 1976 that does not shut off with the key: I assume it is a vacuum valve issue? Also the ac does not work, have you guys converted to r134, maybe used envirosafe to charge it instead of r12?

Anyone know of a good mercedes shop I could take vintage mercedes to get checked out in Arizona?

Thanks for all the info so far guys
