Re the fuel smell. Check under the hood first. The 74 model is a Djet (has Djetronic fuel injection system). Check for fuel leaks in the fuel distribution system. The short hoses that connect the metal tubing (we call them rails) to the injectors are prone to leaks. Leaks around the engine can result in fires! Unless it's already been done, I would buy new fuel injection hose (It is 7.5mm ID) as one of the first jobs. This along with other safety items like brakes & seatbelts. Cosmetic items can come later!

If you look in the stickies, you will find one called EGV107. That covers all 107s.
In there, there are also sections on Djetronics. (especially section 07.4 and 07.5). There are also links to on-line manuals. I tend to use this one (which is not in stickies): Model 107 Maintenance Manual Index

You will also want to get access to the Mercedes epc (electronic parts catalog). Best way it seems is to check eBay for auctions for Mercedes WIS/EPC . WIS is only for later cars, but WIS covers all Mercedes.

Good Luck with your new "hobby"
