The 240 D is quiet a different car than a turbo charged 300 D or SD is, I have both a 74 240 D and an 81 SD and to say one is my favorite would be like a parent picking one child over another. My 240 is manual,and it sort of reminds me of a 2002 BMW with a John Deer engine. But once you get used to it's lack of blinding accelration and learn how to use it's tourque range I find it very fun to drive especialy on back roads, it's only real problem is that it takes a lot of road to pass another car and you do a lot of shifting on grades.
The Sd however is of course a much larger and more refined car,you can drive all day with out tireing. It's accelaration is fine once you get used to taking off in second gear and once up on boost it will pass and climb grades feeling more like a gasoline powered vehicle.
