My dealer included em for free (I asked) as part of my deal. Had to pay for the frunk mat though.
Weather mats are a non negotiable for any car I buy.
Well worth it....
I ceramic coated everything.... I.e. windows, sunroof, but...applied wax to the lower head lights etc.
I have applied to my car windows for 30 years now (back then..I applied waxed).
Heck...I even apply spray ceramic on my house windows after cleaning them 😂
Makes a huge difference...
I don't... I am of no help ?
My assumption...the clear coat is probably not the best given the price point...and will fade over time (Macan sits outside or no?).
An extra layer of good clear coat before installation might be worthy ....or a decent UV protectant spray you apply every 3 mos...
