Yesterday it hit 90 degrees. Wife and I headed out to lunch. Parked in the sun, came out after lunch and I feel like we both suffered 3rd deegree burns on our backs.. Holy crap the seats get hot!
Whenever you leave it outside unattended, just tip the seats forward. That keeps the sun off the back and seat bottom. It helps save your hides from burning or melting into the "vegan leather" interior
