So I did all of the above 4 years ago:
The second day I had my car I took it down to professional eclipse window tint (
proeclipsetint.net). The guy there did an excellent job. I haven't had any issues with my tint. Only charged $200
On the third day I took it to esoteric detail (
esotericdetail.com). Todd the owner is very friendly and does many exotic cars. I had my car first paint corrected. There were numerous water marks etched into the paint which needed to be worked out. Then they put on XPEL ultimate and then covered it with a protective coating. At the time of my install the XPEL was done by an outside person but since then esoteric is doing it in house. My XPEL install was okay. It's not the greatest. You can see the edges if you know what you are looking for. It still does the job and been happy with the XPEL
As for the dashcam I put in the Blackvue 650. I did the install myself. It is actually pretty easy. It does take a little time but the difficulty level is low.
Come out to Columbus and I am pretty sure Supratachophobia and I would love to discuss more and show you our cars.
