I previously owned a G35 coupe... And as I posted above my wife had the G35x sedan. Both were beautifully designed, with great engines, amazing stock exhaust note on the coupe, and great handling... and all this was ruined by HORRIBLE dealer service (not one but MULTIPLE), lies/deception right from the day of purchase, and some of the worst long term reliability of any cars that my wife and I have ever owned. It's a shame because my wife REALLY liked the steering feel of the G35 but we both have vowed to NEVER set in foot of another Infinti dealer again. Oh and the Navi systems were pretty bad too...
While I certainly wouldn't judge an automaker or dealer network based on a couple of bad apples, nor based on a car w/ numerous issues (possible to get a lemon w/ any make), at the same time, I can certainly understand how those experiences would alter your decision-making.
As for the G35 coupe - great design which still holds up today (the original G was better than the G37C which ruined the clean lines); the G35 sedan, otoh, was OK.
The G35C also drove well w/ the one major blemish being its chinzy interior (not really better than the interior of the Genesis coupe today).
With the new Q50 sedan, supposedly the new fly-by-wire system took a lot of the
sport out of the new model (hear that the Q50S is better and that
Infiniti is recalibrating the system).
I think it is mostly because the Germans have been discounting their prices a lot more than before. Part of that may have to do with currency exchange rates.
So have the Japanese due to the falling Yen.
More has to due w/ the proliferation of lower priced 4-banger models for the Germans.
Many buyers would rather get a German
badge and opt for a 4-banger than get a V6 Japanese.
And now
Cadillac is in the game big time and buyers have another option (not to mention Hyundai/Kia).
The RL has never been a big seller and is only one the Acura models. Also, you are comparing BMW sales against Acura, when you should be comparing BMW sales against Honda sales for all their brands.
Why?
When it comes to Hyundai, would compare Genesis sedan sales to the 5 Series, etc. and not Hyundai vs. BMW as a whole.
That has always been the case. The ES was always the bread and butter of Lexus sales, with RX also a good seller when cross-overs became popular.
But it's even more so the case now.
The GS/LS used to sell as much as 60k together - far more than what Audi did w/ the A6/A8.
Nowadays, the A6 outsells the GS.
And FWD sales have increasingly made up Lexus sales and that will only increase w/ the addition of the NX.
As long as Lexus remains reliable, and German cars are expensive to maintain, then the Lexus brand will survive. But keep in mind that Lexus is not a company, but just one brand of Toyota Motor Corp, the largest auto manufacturer in the world.
Sure, Lexus will survive, but it's surviving on sales of its FWD models.
Akio Toyoda had to be talked out of canceling the GS and they have been very slow to replace the aged LS460 (opting for a 2nd, more significant refresh over a new gen model).
Toyota is trying to squeeze every penny from that platform and powertrain (the 4.6 V8 in the LS460 is horribly outclassed).
