Austin has similar winters, obviously at just 200 miles south, but we usually get even less snow than Dallas.
The main reason that the PRHT interests me is the ability to not deal with a ragtop at all, (literally zero exterior vinyl or cloth upkeep), but to still have a convertible option.
That said, I am looking at the MSM a little more closely every day. Want to loan me your car for a weekend? ;-)
