I have a 1985 300td, I was wondering if anyone could suggest a good repair manual for this car. thanks a lot

Some people bash on the Haynes version. But in general (and for the price)
I have found it useful.

Here is a link to an online version that you should really get use of:

You can also find a under $15 version on CD of the Factory manual
on places like Ebay.
