I saw some neoprene seat covers at a website.., they were made for a Eurovan.., not sure if the Eurovan front seats are the same as in a Carat Vanagon.. 

One design they had was solid gray in the middle of the seat and back, and solid black around the perimeter.., 

Then I was in Best Buy and saw some neoprene carry things for wine bottles, in solid red or else in solid black with solid gray on the side with black stitching.., and these looked excellent in the visual feeling of the material.. 

If these seat covers are of the same quality neoprene.., they would be very nice indeed.., 

In fact its made me wonder.., if it wouldn't be a good idea to cover the side panels of my carat, for the front doors and the sliding door, in a gray neoprene..., .., at least then rain water wouldn't mean much.., 

For those of you that don't know.., neoprene is used in scuba diving wet suits.., and they would make even more sense in a Syncro.., which might drive through a river bed..,
