Had to replace the top, vinyl windows became very difficult to see through.
This is a wonderful vehicle for someone like me, who is just starting driving. It makes up for the lack of acceleration in torque and towing/pulling power. I have never been in a situation that the 4wd hasn't gotten me out of, and as rugged as it is on the outside, it is very comfortable on the inside, despite the lack of cargo space.
I have not had to replace any major parts on it or make severe repairs.
In regards to the discoloring of the vinyl windows. I own two Trackers, a CJ7 Jeep and an Mx5 Miata all with vinyl windows. A couple of years ago I purchased a car polish from a friend with the brand name of Race Glaze, polish sealant. It apparently has a very, very fine grit in it and works terrific on windows. You don't have to rub long or hard to get the windows to look clear and new again like some products I have used on aircraft that sometimes takes hours to get to work. The directions or instruction of this product makes no statement that it can be used for this application, however, I use it for all my cars and have some friends that do so also. It saves a lot of money and makes the car safer too.
