I found this statement on www.verticaldoor.com
They are in Ontario CA.
Custom Vertical Doors
Start a Group buy for vertical Doors
We need (10) for the same car, and the same year
Each VerticalDoor.com kit will be 1599.00 Each
After we get 10 orders, we will start on the verticaldoor.com kit
Please do not e-mail us regarding this group buy until you gather all your orders
We do not do custom kits for individual cars
What do you think you? Is this cheap?
