Boxster California...
I used to drive all the time to the beaches in Northern Germany and Denmark. Some even allow cars on the beach. And yes...the Boxster is perfect for the beach, sand and dunes.
What the Boxster really needs is a foldable sun shade, which spans over the entire interior and 2 boogie board holders would be cool too.
Should be easy to design and engineer. What I did today (just to keep the sun away) worked, but that's it. I might put that on my project list...something cool looking...for the beach...Boxster California.
P.S.: SAND is a nice souvenir, which you can enjoy even after years in your car. But hey...
