Heard great things about EVS motors. My brother went there for xpel service on his hood, front bumper, and mirrors...turned out great. I haven't been to this place personally but plan on taking the M3 when I get it.

I went to suntint in Stafford for huper optik tint years ago. They did an okay job overall. Some windows were perfect but some had too much lint.
