Last year I did a compariable mpg rating using the 1984 190d 2.2 5 spd vs any american car or import of today ,the Mercedes placed 5th.The hybrids we not included for obvious reasons but the real surprise is Mercedes has a really good diesel powerplant for the smart car but wont offer it here in the states.Oh yeah ,and nice find to get a real nice 190d ,the 5spd especially is a nice added feature to these little go-cart fun rides.
