Tesla makes/reports quarterly shipments so there are always spikes in the shipment months.
For example this has Model 3 in top 10 selling cars in Europe https://www.best-selling-cars.com/europe/2021-june-europe-ca... but if you check may or july, model 3 is no where. Makes me wonder if such promotion is paid for (And I am about to buy a Tesla, so nothing against them, just pointing out apparent tactics)
I'm also considering buying one, but Tesla is behind VW in EV sales in Europe overall, so I'm wondering why this is so upvoted and about the angle here.
I am personally buying a Tesla (in Europe) mainly because of the supercharger network. But I suspect the build quality of VW might be better.
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).
