Interesting. I've got no experience in this sort of thing and have performed no planning.

Of course, a Porsche of some sort is at the top of the list. I could see doing it in a Boxster, Cayman, 911 or even Panamera. If it was anything other than the Panamera, I'd definitely go with a manual trans. If that's an option in the Panamera, great, but I suspect that would be tough to find. I think an auto would still be entertaining.

I think before I chose a BMW, I'd go with Mercedes. I've never owned either, but what I've heard, I think I'd prefer the Merc. And if you have the option, chose an AMG variant. It may not be a manual trans, but I suspect for 99% of the trip, that wouldn't be an issue.

I think the time of year and route would be very important, especially when it comes to crossing the Rockies.

I'm going to be watching this thread with interest. I'll likely live vicariously through it.
