Congrats. We bought an ID.3 recently here in the UK to replace my wife's aging Golf (almost 11 years old). We're really happy with the car, despite a fairly long list of ongoing software problems. However, I'm confident that VW will resolve them - eventually!
We also have a Tesla Model 3 in the household too since that's "my" car. Thankfully we haven't had any serious issues with it, except for a handful of relatively minor issues at delivery (bumper alignment, bonnet alignment, some damage to one of the door cards, steering misaligned). In some ways, the ID.3 is the better car over the Tesla, but the Tesla Supercharger network is still the ace in their hand, and the car overall sits in a higher market (and price) bracket than the ID.3 so not surprisingly it does feel a little more luxurious and better equipped inside. However, I think the ID.3 will out-last it in terms of build quality and the basic automotive engineering underneath.
