Hello together, my friend wants to buy a Smart Diesel, because she is very often in the city and on overland, about 150 km a day. Since I don’t know about the smarts at all I wanted to ask you how it stands about the durability: The object of the desire has 104000 km on it and is from 4/2000 should cost 3000 Euro incl. 1 year warranty from the dealer. However, I worry a bit about two things: the small engine with so much km ? I once heard of a mechanic that the smart petrol engine has to be a revision of the engine at 60,000 km, is that true? If so, what does it look like with the diesel? many thanks to you
