I'd buy something I wouldn't mind leaving in Mexico, and have fun.It is not Rubicon, but considering that many section need low range and either long suspension travel or traction aids, it is a difficult route.
To reiterate what I already mentioned, it took us about 4 hours to cover 40 miles of that route in a RR Classic - and we drove pretty much as fast as we could (and broke one shock in process).
That's a good question. I'd spend some time in Death Valley before hitting the Baja circuit.
