For Lexus LS I would also consider the brand. Do you need OEM or aftermarket?

BlackVue DR900X Plus for Audi RS 7 - can only recommend!

For Buick Terraza I would also check the warranty. Do you need extended coverage?

I agree with Kenwood DMX907S. Have been using it for about a year and am very satisfied.

Interesting question! For Lexus LC it also depends on your driving style. What's your main concern?

For Ford Fusion Energi definitely Thinkware U1000 Dash Cam. Very good quality for the price.
