Measure the glass and the storage problem
Record the widest and tallest usable glass, mirror and sensor housing, dash depth, side edge shape, and the space available for a folded shade. A shade that is too small leaves heat paths; one that is too large can bow, press trim, or make installation frustrating.
The Google sunshade rows are a small signal, not a best-product verdict. Fit and storage are separate jobs, so keep both in the worksheet.
Limits
No shade, windshield, sensor, heat gain, or visibility condition was tested. This guide does not provide a universal temperature reduction.
