5. BMW-Glas 3000 V8

In the early ’60s, BMW experienced incredible growth due to the enormous success of the “Neue Klasse” models. The company needed bigger production facilities and decided to buy struggling German independent brand Glas and absorb its models in the BMW lineup (via Silodrome).

The result was BMW-Glas 3000 V8 coupe introduced in the late ’60s, which was basically a Glas design but with BMW mechanics and badge. The car was expensive and sold in limited numbers, never managing to fulfill its potential. In those days, the idea of a premium GT BMW model with a V8 engine was ludicrous. Customers just weren’t ready to pay a high price for BMW.
