Hi everybody

Got a few questions.

Do I understand correctly that the fuel filter for an 88 300e is in the rear of the car and if so, where in the rear trunk, under the car, next to the tank?

I've got a slight cold start problem and once it starts when I put it in reverse the RPMs drop and it sometimes dies. Not a problem when its warm. What's up with that?

My Becker radio when out for reasons I do not know. Would like to replace with something that has a AM/FM CD player. Any suggestions?

Looking for a real good "how to" repair manual for my 88 300e. Any suggestions or recommendations?

Finally, anybody know of a good trust worthy Mercedes repair shop in Marietta, Georgia.

Emilio...welcome.

Fuel filter is underneath the car, under the rear seat behind the passenger (US) side, next to the fuel pump.
Do a search for cold start problems using the search function near the top of the page.
The Becker radios suck and if you also search the car audio section you can find many suggestions depending on taste, price and such for replacement or refurbishing. I went with a Kenwood excelon MD. There is also a "stereo removal" page in the DIY section (see link above).
The fastlane part shop sells a detailed CD Rom for the W124, you can also get the Haynes manual for the W124.
Hope some of this helps!:)
