Any problems in a normal car wash?

It's like a normal car. Just wash it like you would any other car. The wheel guides is an interesting problem I haven't thought about but I have heard no problems with them.

The car won't "hang" when wet and more/less then a normal car would. None of the batteries are exposed (they are sealed under the rear seats).

Speaking of which... I should really clean my car this weekend.

As for the antenna, one of my very first modifications was to purchase a "stubby" antenna (In my case 2") to allow for carwash problems. I notice no decreased radio reception around the Dallas metroplex, but replace the stubby with the original whip when driving cross-country.

My Dealer always runs my Prius through an automatic carwash after service and even with the standard antenna installed, I've never had any problems. My principal reservation is that "carwash jockeys" in many instances simply do not know how to drive the Prius and require instructions. Mostly, I wash my '04 Prius by hand.
