There are some good dealers - it's a case by case basis. Do find out from local club members where they are. We are fortunate to have a downright GREAT one here in Austin (Maxwell). I absolutely wouldn't let anyone BUT Dave Weaver (viper tech) work on my car, so you see it can be different. Ask around, I'll bet you can find one.
And now for some good natured harrassment ... What the hell are you doing driving it in the rain anyway?
The viper gets all muddy and disgusting, bad traction and you're surrounded by psychotic knuckle dragging primates strapped to roller skates on ice!! When it rains I drive a Ford Focus ... It's an $8.00 car, Sheesh, who cares what happens to it. And furthermore, how bad can an itty-bitty-widdle leak be in a GTS? In my old RT the water used to lap in over the top of the windshield in great foaming swells. Every car's got it's little foibles ... unless of course you want the soulless perfection of japanese spacecraft gizmology. Enjoy the weather.
As we old RT owners always say - "Moist a$$, warm heart!"
