IT'S crucial to be careful about imports, because you can't be sure about their history, but you shouldn't completely dismiss them. Some that are in good condition, and imported by reputable dealers, can be worth a second look. Get them thoroughly checked by someone you trust, who has an intimate knowledge of the make and model you want to buy. The 300E/300CE Benz is a good choice. They're very reliable, though they are known for valve guide wear as the kilometres climb. You're buying an old car, and it doesn't matter which badge is on the bonnet, it will break down at some time so be prepared.

Think about a W123 series 300D built after 1981. It is a five-cylinder and will give you great service. Little goes wrong with them as long as they are serviced as recommended, and the rest of the drivetrain and chassis is equally durable. Later W124 diesels are six cylinders and are also worth considering, but cost more. They perform better than the earlier cars but have more electronics and other modern ancillaries to give problems.
