There is NO timing belt, the MB 3.2 engine has a chain driven SOHC, 3 valves per cylinder with 2 spark plugs per cylinder.
The chain should never need any attention.
These cars are really nice to work on, provided you have a good set of both male and female TORX sockets / drivers and a good set of metric wrenches and sockets.

The headlight bulbs can be a PITA, but there are lots of threads here about that.
MAKE SURE YOU HAVE A GOOD BATTERY !!!
