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.
