Are there any shady spots in the parking lot? You could try using special reflective pads that attach to the windshield. Until I bought regular sun visors at T1A Auto http://www.t1aauto.com this was the only way I could protect myself. I’m lucky the car is beige and not black; otherwise, I shudder to think what the temperature in the cabin would be if it were in the sun all day. A friend of mine once got heat stroke after getting in a car like that. Luckily, his wife was nearby and able to administer first aid and get them home. I hope this doesn’t happen to you.
