While I have an incredibly strong aversion to any sort of automatic car wash for any of my cars (honestly, I've not been to an automatic car with anything other than a company owned vehicle in over 30 years!) my primary concern for taking a Crossfire Roadster through one would be all that soap getting on, and into, the fabric of the top. Even washing my own Roadster at home I never get the wash solution on the top as you can never get all the soap out. Try this: next time you do wash the car at home, when rinsing it to start the process give the top a good blast with the hose and you'll probably see soapy foam come up. Not a good thing for the long haul.
