I'm posting this in both the 3 and Y forums. So please respond to the one that you own or know more about.
I wasn't going to consider a Tesla as a choice until this whole EV tax thing that took place a few days ago and now the car I was thinking of getting is no longer an option. I was thinking of a Audi Q5e. Also on the back of my mind was the BMW 330e/i4 and Mercedes C series. Not all had tax breaks, but all would be something I could get.
So I was thinking between the Model 3 Performance or the Model Y.
1) I never liked not having a instrument cluster in front of me. Wouldn't be too bad if the car had a HUD. Now I noticed there are some aftermarket screens one could install on their own. And it looks ok to install. Would something like this void any warrenty?
2) About the Premium connectivity... Is it worth the $9.99 a month? I read the info on it. Just curious on people who actually use it.
3) Can I have the car connect to my Phone's hotspot and not use the Premium? I heard you can do the opposite, connect your mobile to the car's hotspot? Is the speed ok?
4) 3/Y- Which has better lighting at night? Do both come with fog lights? Are there upgrades to the lights? For the USA are they adaptive?
5) 3/Y- Interior lighting, what kind of lighting is there? footwell? Glovebox, etc? Do they change color? Or just std white?
6) About the Autopilot. I like the lane centering, traffic start/stop, cruise control. In order to get that much, do I need to upgrade ENHANCED autopilot? I never really used the auto parking in the cars I had them with. I hate driving by a stall and having the car autopark because if there is a car behind you, sometimes they are pain when they think you don't want that stall and follow you too close that now you can't reverse in.
7) About the cruise control, can you tell it to ignore the speed signs? One issue I had in a car was I would have it set for 60mph, a large turn would come up that said 45, the car would slow to 45mph and cars behind you would have to break and then it would slowly pickup to 60mph again. I didn't like that.
8) 3/Y- I thought I saw picture of one of them having active spoiler? Is that true? I don't seem to see that as an option.
9) 3/Y- are the cars really that wide? The length will fit into my garage space, but width seems big. My old car is 72in wide, while the 3 is 73in and the Y is 76in. And supposedly these two cars are smaller that my older vehicle.
10) 3/Y- Do either cars have warning lights in the mirrors to tell you there's a car in your blind spot?
11) 3/Y- How are the seats? I noticed there's no options for them. Are they easy to get in/out of?
12) 3/Y- How are the cars when you drive? Are they harsh with the 20's? I live in an area with a lot of potholes.

How's the ground clearance? Do either cars have adaptive suspension?
13) 3/Y- I take it, it's power everything? Power adjustable tilt and in/out for steering wheel?
14) 3/Y- Does the car have memory for seating position/steering wheel, etc? Do they move in/out of your way when exiting/entering the vehicle?
15) 3/Y- I take it the cameras in either cars work the same? Can you view them whil;e driving? Example: I'm changing lanes, can I view the side of my car? I think Hyundai had a car like that. Can you pick and choose views while parking?
16) 3/Y- Are the audio systems the same on both cars? Or does one come with a better system? I keep reading there's a standard audio and premium, but when building either cars, I don't get options to pick? Is the only way to get my music is to put it on a usb stick and leave it in the car? How easy is it to navigate the menus to play music?
17) My wife and I use Apple and Android carplay in the car. I thought I read that tesla opened that up to the cars? But now that I'm interested, I can't find anything except stuff people added themselves.
18) I take it Waze don't work, huh? I know the Audi, I had to either choose that or the built-in map the car. Waze won. I kind a like the extra security features it offers.
19) That all glass roof. Doesn't it make the car hotter to park outside durning the day? No way to cover it either, huh?
20) Lastly, besides trunk space on the Y, is there anything else that makes one better than the other?
