We've had our Model 3 since July 2018, having reserved it way back in the mad rush in 2016. The Model Y simply wasn't a thing yet.
We have been stymied a number of times by things we can't fit in the back because of that 17-inch vertical clearance under the shelf. So we dream and drool from time to time about an upgrade to a Y.
It's interesting several of you report poorer handling in the Y. We're both pretty conservative drivers, not going to the track and such, so I wonder whether we'd care. That is, do you only really notice the handling difference when doing edgier maneuvers?
Also, a bunch of you mentioned ugly. Now, that's interesting. I think all four Teslas look essentially similar, but most especially the 3 and the Y. (The Cybertruck will shatter the pattern.) Obviously the Y is taller overall, with a bigger nose and ass. But I've found so many people can't even tell them apart unless they're side by side. So I guess I'm okay on the ugly index. The handling I want to know more about, though.
And then there's towing. The Y is rated to drag up to 3500 pounds around. We've been thinking of a small 2-person camper trailer. That'd go nicely with a Y. And when we're not doing that, we could have a hitch-mounted bike rack to take our bikes on adventures, like we used to with our old Prius.
So we're still thinking. Maybe the electric F150.
PS: our 3 is in the Tesla hospital in Bend at the moment, and we have an X as a loaner. Now
that is a big car! It barely fits in our garage, and it's way taller. But it was great when we had three grandkids in car seats last weekend!
