This years trip to Florida from Michigan via Maine was nearly 3000 miles. Nearly 1700 miles in the rain. No problem with some minor modifications of the car as gleaned from the SCORE sight. I also added a neoprene rubber (garage door) seal under the top seal to the rear and under the side curtains. Defrosters worked great and even in the inclement weather my wife and I enjoyed the trip. Top was on from Niagara Falls to central GA. Has not been on at all down here in Fla. Driving back to Michigan at the end of the month. don't let the weather scare you from enjoying your car.
Skyline Drive and Blue Ridge Pkwy.
