Just took delivery of a Model Y in the US (Fremont build, VIN 249XXX), the quality is top notch. No paint issues/blemishes, no missing parts of fasteners, everything checked out (using this [1] checklist).

The ones we are getting in Europe are still from Shanghai, not sure if that matters.

It does, units rolling out of Shanghai Gigafactory are of higher quality than Fremont. Based on reports of Model Y quality from various production points, can't go wrong (imho) with getting one regardless of where its being built. Looking forward to seeing the quality of those from Gigafactory Austin with Tesla's new single cast operation.

is there a similar checklist for model 3?

You can use that same checklist I posted. There should be almost no delta except perhaps interior seating configuration. To confirm, "Model 3 checklist" returns several results, all of which seem comprehensive at a glance.

> mainly because of the supercharger network

I always find it amusing that people who use the internet think there's value in a closed network. You might as well be using AOL.

But the good news is Tesla claims that they will finally open their charging network to other brands:

Tesla is doing this now to get access to government subsidies for charging infrastructure. Governments aren't going to fund single brand chargers.
