Yay. I placed an order today for a Covercraft UV Heat Shield that's custom sized/shaped to the R32's windshield No more worrying about the pounding sun on my leather seats. It happens every day since my car sits facing that way in a train station parking lot.

It's more $$$ than the one size fits all cheapo windshield heat shield but I'm convinced it's going to be worth it. If anyone reading this decides to buy one, the link I gave above is to the dealer I found had the absolute lowest price and free shipping. I have no association with them but the Covercraft site lists about 23 dealers and I took the time to price them ALL. My final cost including the custom storage bag was $48.30
Here's product info from the Covercraft site:
Custom-Patterned UV Heat Shields for Front Windshields
UV Heat Shields help reduce interior temperature and protect the interior from damaging sun rays that penetrate the front windshield. Our heat shields are custom patterned, insulated and available in two styles. Custom patterned to follow the outline of the windshield, we have over 500 patterns to fit most popular cars, pickups and vans. Front windshield UV shields provide protection at the beach, work, airport...anywhere you park, and they're easy to use.
UVS100™ Heat Shield
This premium quality, custom patterned, folding heat shield has a silver reflective fabric on the outer side, soft felt on the inside. Both fabrics are laminated to a foam-core board which acts as an insulator. The silver outside facing fabric helps reflect damaging UV rays that not only heat the inside of your vehicle but also damage the interior. Your steering wheel and seats will be cooler with the use of a Heat Shield!
Easy to use - just unfold and position across the windshield surface, then fold the sun visors down to hold the shield in place.
