As the outside temperatures rise, the car is more prone to having hot start problems, that is if I want to start the engine within 5-10 minutes after an "extended" drive (usually +1 hour). Letting the car cool for a while makes it able to start again. The ML 500 and the 400 Cdi have exactly the same price here, so one must made a choice. One argument is the resale price: the diesels have here (Italy) a much better resale price (especially the 270 Cdi). You can got a good value for your ML320 but a 430 is very low priced after a couples of years. The Mercedes-Benz OM642 is a 3.0-liter turbocharged V6 diesel engine that became available in 2005.
