$375 to tint a wagon is likely pretty cheap tint. Spend the money on Huper Optic, 3M Chystaline, etc. Well worth the extra money. You can run lighter tints and get better heat reduction with the high end stuff.
The Bra price seems about right. It ain't cheap by any means. Although with CW you won't see the chips as easy as a darker car...so the bra might be less appealing if chip prevention is your goal.
