Lyriq XS Wear Lease Protection - GMAC

I am getting close to pulling the trigger on a Lyriq 24/10 lease. Considering a teen in the house will be driving it some, I am expecting dings and scratches.

What is the dealer cost for the XS Wear Lease protection on this car for 24 month lease?

Benefit is a maximum of $5,000 coverage, and no more than $1,000 per item. Also $400 extra mileage fees, which I don’t believe we will use at all.

Thanks in advance for (i) the dealer cost; (ii) what others have paid; and (iii) if there are other dealers that will sell it or if you need to buy it from your dealer.

Thanks in advance!
