I got the '86 Country Squire tinted yesterday. A local tinter was having a special running and I took advantage of it. The cargo area is 50% and the doors are 35%. Just right for the wagon, IMO. It makes a ton of difference in cooling the interior with the air conditioning. I actually have to turn that AC down now, instead of leaving it full blast all the time. It has a lifetime warranty, too. The same place does stereo installs, too, so they're installing the stereo I have for it at the end of the month. It's enjoyable to drive again.
Running the AC on lower will give a better fuel mileage. Soon you will be getting 40 MPG as is claimed for those engines. It does look nice.
