Try transcend 810
I am using [h=1]SanDisk Ultra USB 3.0 16GB Pen Drive[/h]at15-20mbps speed
I am happy with my 810 since it is shock proof and water resistant. I have a habit of dropping my pd a lot.
Both the options mentioned have USB 3.0. And as I mentioned looks like Car Stereo doesn't support USB 3.0.
There is no such thing as a USB 3.0 only pendrive.. Every USB 3.0 pendrive is basically a USB 2.0 PD with 1 pin extra for more juice while transferring data.. The PD on your car didnt work for some other reason, perhaps file was incompatible, had a higher bitrate than your stereo can handle or the entire file system was wrong.. IDK but you have to try again, maybe borrow a friend's PD and test
