7: BMW E3 3.0Si
The BMW E3 is often highly regarded when it comes to the sports car segment from this period. Released in a wagon version as well this was one of the original sports wagons that you could buy. But, the value of classic BMW models has gone to new heights, and this car is way overpriced for what it is (via Car Review).
Getting a BMW from this era or even the years that followed is problematic, because parts are hard to find, and a trustworthy repair shop is even more difficult to find. The E3 should be avoided if you want a sports wagon from this era, at least until prices start to stabilize.
