Not decided yet, just in the contemplating phase.

My 300D is in fantastic original condition, and swapping the engine would certainly decrease it's value. However I dont drive it much because it's gutless by today's standards, and not that fun to drive. It would be much more fun if it had more power.

And since I prefer the W115 styling versus W123, my ideal car would be a W115 with a W123 turbodiesel.

There is a rusted out 82 300d with good engine that I could get, and that's what got me thinking!
