From the little pics I can see that the original carpet is missing off the tailgate...along with the stainless trim that holds it down. It's a nice looking car for sure...but think $7500 is a tad high. I agree with the $4500-$5000 range.
Well then mine must be an exception. The gate still wears it's original carpet and trim, and I've never had a problem with the power window rolling up or down.
I was in Europe all of the 80's (except for 10 months). I remember back around 1984 and being in Munich for the weekend. Drove past a Mopar dealer and stopped to look at the new cars. I saw this strange vehicle with a pentastar on it and thought Mopar has lost their mind. WTF a Dodge Caravan? Little did anyone know that it was a game changer and saved Chrysler. I still hate minivans!
