I’ll assume you’re talking about a C200, Kevin, which was the most popular Benz model with a 200 in its name back in those days. The good news is that, no, that engine doesn’t need a timing belt change. That’s because it uses a timing chain rather than a rubber timing belt and, all things being equal, the timing chain should last the lifespan of the car itself.

All Mercedes-Benz passenger cars from that era would all have been sold brand-new with two keys. If you’ve bought the car second-hand with just the one key, you can contact a Mercedes-Benz dealership, quote the car’s VIN and the dealer will be able to order the correct key and electronically code it to work in your car. It could cost several hundred dollars, however.

Is it a minor service? Perhaps it’s a major one? The cost depends on what needs to be done. The best thing to do is to ring around and check a number of service places, from main retails outlets like Kmart, Repco, Ultra-Tune etc., and some specialist Mercedes-Benz mechanics. That would you a good guide.

In terms of reliability and common faults there is little difference between Mazda, Honda and Toyota. They are all good, reputable brands building cars of a good quality with few reliability issues. Choose the one that best suits your family needs.
