I’m a really big fan of OEM+ modifications on cars. Something always feels good about grabbing a part from a higher trim level or even another model and seamlessly adding it to your car to make even better. Lots of times it is something small like a piece of trim or a grille. Other times you go totally crazy and swap in an entire engine from another car. That is what we have today with this W124 Mercedes-Benz Estate up for sale in Atlanta. What started life as an already really nice E320 with the M104 3.2 liter inline-6 was swapped out the M104 3.6 liter inline-6 from a C36 AMG to make a pseudo E36 AMG Estate. As you might have noticed, that wasn’t the only thing that was changed on this wagon.
