Infiniti G35 and G37.
I hate the type of people that buy and own them. High maintenance, don’t know anything about their cars, and they want the Rolls Royce level treatment, but only want to pay for service and parts like it was a 1992 Toyota Corolla.

As a long-term Nissan parts guy though, I actually strongly hate the entire Infiniti brand. I wish Nissan had killed it long ago and just made better (and more upscale) Nissan products (maybe bring the Nissan President to our shores, etc.) and done a better service to the history of Prince Cars and Nissan.
