I'm assuming the vendor in Columbia was Performance off Dobbin? I've had 5 cars tinted there, with mixed results - thought it was my only choice in the area. (I've actually had my 'vette tinted in Glen Burnie... with worse results) I'm considering this vendor in Sykesville, but $350 seems like alot for their best tint. (I have a M3 coupe) Do you have an updated opinion on the work so far?
