I wouldn't be afraid to land anywhere in Mexico, I used to fly to Guadalajara for work and always flew from Del Rio TX to Torreon then on to Guadalajara. Familiarize yourself with filing an EAPIS and plan on arranging a handler ahead of time, it will save a lot of headaches until you get used to...
This, I had a friend that couldn't land 172 to save his life, after a few trips flying the length of the runway holding it just off the ground, occasionally touching down, he started nailing his landings, do it it'll get you on track fast.

I hope I can add a little input, I have an RV-4 and a Bonanza. Before I bought the Bo the RV was for commuting and flew 100 to 150 hours per year. Now the RV is for fun and 1/2 hour to an hour now and then is all it gets used for, 25 to 50 hours a year is it.
I have a 996tt and love it. The only reason it wasn't accepted right away was the liquid cooling. The only issue I've had with mine is the ignition switch, and tires (if I let my sons drive it). ;)
