I don’t necessarily agree. I drive a Taycan, the wife drives a BMW iX. Reliability was definitely a factor in purchasing both. Both affordable in respect to our incomes.If you can afford any of the three, reliability isn't really a factor in picking. I just don't personally like BMW styling. Overall I definitely prefer Audi, but the Mercedes interiors can be really nice.
In the past, we leased a Range Rover, and that thing was constantly at the service center…radiator…air suspension…got rid of it in 8 months.
So no matter how deep your pockets are, relatively speaking, reliability is still a concern. No one wants to waste time at a service center, or use a loaner while waiting for parts to arrive from overseas.
