Mercedes Benz E Class 300 Turbodiesel

If you maintain them, these cars will last. Change the oil(s) regularly and keep on top of the corrosion problems.

This is one of the last Mercedes diesels you can buy that I call 'Old Technology'. A straightforward Turbodiesel, no commonrail or computer controlled injection etc and as such its mechanically simple and therefore reliable. I know of one that has covered 500,000 miles as a taxi without any major work. One review sums it up by saying the engine is only suitable for commercial applications, this is a massive compliment if you want an engine to last your lifetime.
