I'm also trying to avoid seams/edges, but can't bring myself to pay the premium for that.
Prices here in SD:
Full front: $1800
Full car: $5k
Add $1k if you want all edges wrapped, and minimal seams.
A place in LA quoted me the following for seamless/edge-less:
Full front: $2500
Full car: $8500
I want to fully protect the car, but sheesh, that doesn't leave me any $$ for tint or ceramic coating.
