It is possible that it was purchased new in Germany, but was US equipped, in which case it would be a US model.

If it is indeed a Euro model, there are some differences. For one, it originally had real headlights instead of the sealed beam jokes that went on US models. It could easily be that they have been changed out for US headlights.

Another difference is the radio antenna located on the passenger front fender instead of the US model with the antenna on the drivers rear fender.

The other key for identification is the bumpers. The Euro model has short bumpers which are what the designers intended. The US models are several inches longer and make the car look a little funny.

The US models were all top of the line as far as interior and trim goes. The Euro models are everything from stripped down, cloth and no wood interior with manual steering, to leather with wood and every possible accessory.

If you want to see what a Euro model looks like, you should be able to search my posts and find the picture of my '84 Euro 240D.

Good luck,
