I agree. I like BMWs for what they are but I wouldn’t dismiss Cadillac’s current offerings without taking a real look at them. And really who couldn’t get excited about the CTS-V?
Porsche is at least offering something unique in their rear engine models. But at the same time they aren’t really practical for day to day use. Noisy, cramped, very low to the ground (so visibility is not their forte). And even more expensive to maintain.
I have driven a few. For what I need my car for, I prefer my BMW 535. I don’t race. 99% of my driving is 65 mph or less. I also have a wife and a kid, so a de-facto 2-seater is out of the question even if I did love it.
