I've been a life-long Mustang guy, (86, 92, 95, 07 GT's all heavily modded). My last Mustang got totaled when a guy made an illegal left turn in front of me. I ended up deciding that maybe I should "grow up" and get a sensible car, so I ended up going with a 2018 Maxima SV. The lack of aftermarket for that car really shocked me. Especially after how good I had, had it for so long with the Mustang.
After having it for about 2 years I just couldn't stand the FWD any longer. Plus I was always afraid of the CVT going out. So last weekend I traded her in on a 2018 Q50 Luxe. So far I am liking the car but still getting used to it, (the 2 entertainment screens are kinda confusing, never sure what can be controlled by the jog dial).
So far I've heard that the things to look out for on the Q are the serpentine belt and leaky turbo's. I am surprised at how much worse the gas mileage is on the Q compared to the Max. Other than the turbo's it's the same engine right?
Anyway my first mods are going to be rims and tires and springs. After that, who knows? I don't think I'll get too crazy with this car. Maybe just exhaust and a tune.
Hah the Altima/Maxima use to have a pretty strong after-market in the early 2000s when they popular sleeper sedans
but they've moved more into family haulers than anything. So wouldn't be suprised if the aftermarket
dried up pretty heavily.
The Mustang tuning community is massive however so its hard to compare it to anything except
the other most popular of tuner platforms.
As far as the engines go the VQ35 and VR30 are very different motors as others have alluded too, in practice
VR30 is closer to the GT-R engine but downsized and with various tweaks and technology for mass-production to keep
Hence the VR engine code although there is some overlap with the older VQ motors as with
any modern engine.
The Serpentine Belt is pretty easy to deal with if you simply swap out to a Gates-Belt and have the tensioner pully alignment checked
after that most don't have any issues (a good check every oil change though).
The leaky turbo seals is the largest issue but Infiniti has been good about honoring warranty.
