I just installed the Pedders Extreme XA coilovers on my 2012. I only went this route because my original stock suspension was starting to show it's age. I have 1000 kilometers on them now and am happy with them. They have 30 position adjustable compression/rebound damping and mine were preset...

Vinyl is very reasonably priced but you'd have to find a local guy to install it. They can also do just about any colour you could...
In addition to the advice above, Pop the trunk as well and just leave it down without fully closing in in case you need to get into it with the battery disconnected. And that advice with the wine corks is gold! Thanks for that idea.
