The Show'N'Shine is a friendly comp between vehicle owners that also allows the public to enjoy a collection of vehicles in one place. It can give you chance to see what others are doing in the EV space, ask questions of people in the know and also get some ideas on the kind of EV you would want.
You can see some of the entrants for a sneak peek at the Show'N'Shine page. However, here's a quick coverage of some now:
There will be other vehicles there on the day and some will be run on the track to show what they can do. Make sure you set time aside for this event when you attend the expo.
