3: BMW E3 3.0Si
BMW was just getting into its own in the 1970s and the E3 3.0Si was evidence of that. The styling of the car was about as noticeable as possible. But this was at a time when cars on the road were large and the E3 was anything but that. The performance is what made the 3.0Si stand out from the crowd, and to this day it still holds its own (via Car Review).
Perhaps the BMW E3 3.0Si is responsible for giving BMW the slogan of ‘The ultimate driving machine,’ because it did it well. Although you used to find these for a bargain, the value has been spiking up. As more enthusiasts seek out the M-Series cars, the E3 is a notable exceptional that offers great performance.
