Many of the MS and MX touch points were actually Mercedes.
You’d expect a company to learn from its mistakes but in parallel Tesla are reducing cost dramatically. The paint shop has been a known manufacturing limitation for a while (something to do with the ventilation) and that’s why we get limited colours and big batches of same colour cars go through. I suspect white is also quicker to paint or cure which is why it’s free but I couldn’t tell you why. But either way, paint seems to be a ‘JFDI’ activity and the balance between learning and cost cutting is a hard one to judge. Tesla are certainly taking liberties everywhere with customer service, warranty, FSD promises because they can, so why wouldn’t product quality be on than list too? The bits of wood holding a heat pump in place on a MY says to me getting cars out the door cheaply is the only goal. But equally the addition of a heat pump is moving them forwards.
it’s the old adage about 2 steps forward, 1 step back, only some days it feels like 1 step forward, 2 steps back. What matters to you might not matter to someone else, either good or bad.
