swamp: tintplus in laguna hills did a very good job on my 335, OC 335i's 335, and my M3. they do a great job with the dot matrix, OC Kid complimented on their work.
regular FormulaOne tint is about 200, i did ceramic FormulaOne Pinnacle for 440 bucks. tell him Nabil with white M3 sent you if he asks for more than that (coz that's a bit discounted price) so he should give u at least my price. Ask for Mark (talks a lot but super nice)
if ur in the area buzz me too... i can come and get u for food or something by the time ur car is getting done.
