$500? Pretty sure it's $1200 EACH unless the price has come way down. I treat my panels like gold as I really don't want to have to foot that bill to replace one during the life of the vehicle. Though my front panel has a VERY slight hump on the driver's side. I can tell at least once a bit of water got in, but cannot recreate it using hose or checking after huge rainstorms, but the leak was right where the hump is. Gonna attempt to get a new panel under warranty. I was given the impression they're made with the same material as Jeep Wrangler hardtops.
