Last September, some nut job paid $176,000 for an early 2000s BMW sedan. To be fair, this was an E39 M5 — BMW’s greatest sports sedan, ever — and it had fewer than 500 miles on the clock. But $176,000 is $176,000.
If you’re looking for a Bavarian bargain, consider aiming instead for the forgotten generation of the M5: the E34, produced between 1988 and 1995. For decades, the executive-sized powerhouse has flown under the radar, largely due to the fact that it was iterative, not innovative — an evolution of the original E28 M5. But it was also the last M car assembled by the hands of actual Germans. Today’s BMW performance cars are all put together by machines.
The upshot of all this is that you can buy a certifiable classic M car for well under $20,000. But as with the purchase of any old performance car, there are a few things you should know in advance.
Performance

As an evolution of the E28 platform, the E34 was the second (and last) M5 in the lineup to make power from one of BMW’s vaunted inline-six cylinder engines. The displacement increased from the former car’s 3.5 to 3.6 liters, and it produced about 310 horsepower. It would also churn all the way up to 7,000 rpm.
