Regardless of whether this is a 123 or 124 car, given the mileage I believe this car is overpriced. That said, I would love to have it either way.

There are many subtle differences in a Euro and US car, but none that would make the car inferior IMHO.

I think the 124 diesel cars were 2.5 liters only, but I'm not at home where I can check my books.

Good luck,
