Intro-Tech AutomotiveMD-64-R Ultimate Reflector Custom Fit Folding Windshield Sunshade for Select Mercedes-Benz X166 GLS 450/550/63 Models, Silver

Just an FYI to save anyone the trouble… This does NOT fit the 2020 GLS450/550

Works great and fits perfectly.

It good

Fits like a glove on my GLS-500.Very good quality.

this is a quality sunshield, not some flimsy pos. Fit the windshield perfectly and has the thickness to be effective here inArizona. I have one for both of our vehicles.
