Things have went up tremendously in the last 10 years. I have been using the same painter for 20 years and we have gone from $5-6k for a color change full paint job on a BMW(4 door) to up around $10-12k for a non-color change repaint on a straight E36 M3. New gaskets and seals, windows out, misc trim pieces here and there. It's so expensive now to do good paint jobs with quality materials and a painter who stands behind his work.
That's crazy. Do people actually pay that much for a re-spray? Given those prices, I can see the wrap being a bit more economical.
