There are also slight differences in the doors of the 109s so that they accept the chrome trim.

What I mean is that a 280SEL front or rear door won't fit on a 300SEL because it has no provision for the extra chrome trim.

This is an often-overlooked difference between the two cars.

The 300SELs also had a bit more wood on the interiors, and normally used a higher-quality or rarer wood such as burl walnut or macassar ebony instead of the typical maple found on the 108 cars.

Cheers,
