i see a 88 or 89 crx no back window is it worth bing and how much should i buy it for

 

how many miles is on it, what kinda shape it is in.

 

You can pick up a new back window from a wrecker. Hell, you could pick up a whole back end from a wrecker. I'd get a price quote on the part first, then bargain with the guy to remove the cost to fix it from what he's asking.

Heck, most of the rear windows at the wrecker's are even tinted .
