Don't do it. I know first hand. The v12 is not the issue. It's the rest of the car. Built poorly, and the design is just a pile of work-arounds for problems they don't fix correctly. Here's an example.

Problem: Fuel boils in the lines due to congested engine bay and improper ventilation.

Solution: Install a fuel cooler that hooks up to the AC and then make the AC compressor always on.

Result: Even poorer economy, more heat, worn out AC compressors, and a car that runs like crap when the AC breaks (oh, it always breaks).

Get a Benz if you want fast comfy cruising. Lots to pick from.
