That is how I see it. The designer of the Model 3 is from Mazda. I think the basic exterior looks like my car. You don't have to agree. Honestly, if you want to talk "any Mazda trim" when compared to the BMW, I would say the highest Mazda3 interior is way nicer than the interior of the Model 3 (mainly because I don't think the interior in the Model3 is that good, not that the Mazda is excellent, although it always gets a nod for being above it's class). So the interior of the Mazda is better, the exterior is very similar, and the drivetrain in the Model3 is way better. That is what I said."it's basically my car but with really good performance."
Sure they want to compete it with the 3 series, they need to get that kind of money to make a profit.
