We have a Model S on order that will go into production soon. The one thing I am still on the fence about is the sound system. Many say the upgrade is only bass-related and not worth the price, but as someone who hugely appreciates good sound I would feel a lot better if I could hear the standard version for myself. Unfortunately all the demo cars at the Natick Mall have the UHFS package, so I had no way to test them side by side. I realize this is a big ask, but if you have a standard sound system in your MS and you're in the Boston area and wouldn't mind letting me listen to some music files on it (no driving!), I'd be very appreciative and happy to buy you some beer or wine of your choice.
