I guy from work drove his brand-new Model 3 in today and was gracious enough to give me a tour of the car and a quick ride around the block.
I've test-driven a Model S before and ridden in one a couple of times, but I'm certainly no Tesla expert. The 3 seemed extremely quiet from a road noise perspective, and the upgraded stereo cranked. The screen was bright and easy to use, the climate controls are dead simple, and the spartan dash made me feel bad the minute I got back into my car. I didn't want to go back to the world of buttons and levers and indicator lights. I'm a little sensitive to bright sunlight, so I was very concerned that the glass roof would be a problem for me, but it's well-tinted and was not the least bit annoying even on a bright sunny California day.
The door handles look like the Model S, but they are manual. You push on the end of the handle and the other side pops out. To exit, there is no handle to pull, just a small button. The interior materials seem high-end, with the exception of the middle console's front sections. I'm referring to the covers on the storage areas that are made from a glossy black plastic and look like they would scratch easily. While the Aero wheel covers don't look too bad in person, mine will look much better in a box in my garage.
There are some software bugs that still need to be ironed out, like you can't stream music from your phone over BT yet and there's no support for Homelink at this time.
My delivery date is Feb.-Apr., so I'm trying not to get excited, but every time I turn around, I'm finding another reason to get more excited.
