I used Mr Tint back in Jan and just had them do ceramic and was a hundred or two less (fronts, rear sides, rear). I'm going to have them do my windshield also as I've gotten kind of sunburned almost already. I also bought the $75 mesh shade for the forward roof glass and it definitely helps.
Kind of late, but I just got a quote from Mr. Tint as well and they gave me a price of $550 for front windows, rear windows, and rear windshield. Upgrade to ceramic would cost $775. Maybe they reduced their prices after some backlash?
