I'm going for a new Hyundai car and the sales manager says their cars will have the high end 3mCrystalline tint which is cheaper if i go thru them. He claim that they have an agreement with 3m as they sent lots of car for tinting.

PM BEST PRICE for Hyundai i40 tourer:
1) Nano 70s (side) + Crystalline70 (Front & Back)
2) Nano 40s (side) + Crystalline70 (Front & Back)
3) Ceramic 50 (side) + Crystalline70 (Front & Back)
What is your recomendation for the roof? Nano or Crystalline?

And your location.
Thank you!
