What years have the little window along the rear of the car? I've had a few cars I've taken a look at but they all have the older back end. I like the way the newer ones look, but I'm not sure what year they start at. I'm looked around but some claimed 89s have the window and the newer style, and others don't.

I'm going to be spending at least 1500 for the car now so that opens the window alot.
