Your implication (based on this and your previous posts) that the decrepit
Infiniti Q50 and Lexus IS are objectively better cars than the Genesis G70 due to sales figures is utterly laughable. You brush aside every factor to the G70's sales mentioned already in favor of your personal narrative of it being a bad vehicle. But sure, I'll take your bait.
I dislike having to go on anecdotal evidence, but as someone who rents cars frequently at airports in my business travels, I have never seen a Mercedes or BMW being offered. However, the
Infiniti Q50 and Chrysler 300 are always available as the so-called "luxury" option. Assuming Mercedes or BMWs are offered, I don't expect them to be anything more than an A-Class or base model 3-Series. Meanwhile, you can easily rent an
Infiniti QX80 for chips.
Luxury brands are exclusive by their very nature. Mercedes in Europe is not perceived as a "luxury" brand, as are any of the other other European manufacturers, aside from Porsche, Bentley, etc. Mercedes/BMW/Audi offer base models with less options than a Corolla powered by a puny 4-cylinder diesel that you would never find in North America. Those are what the taxis usually are. Consequently, they don't have the reputation for expensive things breaking in Europe as they do here, because there aren't as many expensive things to break in the barebones models they sell in Europe.
Not sure how Acura is relevant to this topic since they were never advertised as a luxury brand to begin with. They are merely a premium brand, and that has not changed since their inception. Unlike
Infiniti, which struggles to even be considered a premium brand nowadays, Acura has been thoroughly consistent in maintaining their brand level. There's a reason the NSX was released as an Acura here while the GT-R was a Nissan instead of an
Infiniti.
