Between my wife and kids, they have four Beemers. An '80 320i, an '84 318i, a '90 318i and an '04 325i.
They all have their good points, but my favorite is the '84. It is a good enough chassis. small and easy to park, big trunk, doesn't have much fragile body plastic and its electronics are simple to understand and work on.
I would like to swap in the 130-horse engine from the '98, though!
Though I detail and maintain these cars and am a long-time BMW CCA member, my daily drivers are CHEVIES!
