Something to consider...Sorry but I don't understand this statement. You either want the car to look it's best, or you don't.
If you do care, go with Xpel Ultimate and forget about the factory armor.
Option A
1. Buy a 60 kWh vehicle now
2. Install Xpel Ultimate for $7.5K (that's the Seattle price some of us have seen, YMMV)
3. Drive it for 8 years
Option B
1. Buy a 60 kWh vehicle now
2. Drive it for 8 years
3. Trade it in to Tesla for a certified pre-owned 60 that the original owner had wrapped (or repainted)
Assuming the options of the original vehicles were comparable, Option B might be a cheaper route than Option A. Of course, for step 2 of Option B your car might not look as nice as for step 3 of Option A.
