So, I'm in the car market again.
I want an A6. I could afford an A6. But I can't justify it.
I'm thinking -
Infiniti M37: I like Infiniti. I have always liked the M.
VW Touareg: Garbage reliability?
Infinti FX/JX: I like both, but the JX is too big, FX is going to replaced in 2 years.
Audi Q5: I've mocked far to many guys who drive one for me to own one, but it's not my fault that Audi doesn't make something between the Q5 and Q7
I feel like the M37 makes the most sense.
Driven them all. Owned some. You should look at the Jaguar XF 3.0 Supercharged. Fantastic car, same price as the Audi and Infiniti. I'll break down your list first:
Infiniti M37: Fantastic car. Sports package is a must, imo. You probably noticed I just got an M56S and I just can't imagine owning this car without the sports pack. Massive driving improvement, from looks (bumper, headlights, side skirts, spoiler) to performance (better brakes, better wheels and tires, better suspension, etc). Yes, the sports pack is rougher because of its 20s...but if you live in an area where the roads are smooth, get it! The interior is top notch stuff, and reliability is about as perfect as you can get. Plus the user interface for the navi, audio, etc is really good and very intuitive.
VW Touareg: Awful car. Unreliable. Pitiful and slow. Cheap plastics all over with an underserved price tag.
Infiniti FX: Great car. Not a whole lot different than the M37, just taller with an interior resembling the G37/EX37, as opposed to the classier M. Aesthetically not for everyone (droopy headlights are a turn off).
Infiniti JX: It's a minivan, FWD, with CVT. Do you need this in your life?
Audi Q5: All Q5s are either 2.0T or 3.0 supercharged. And all of those motors are unreliable garbage. My cousin has a 2011 Q5 with the 3.2 in it, and the ZF 6-speed auto - which being so late in their life cycle are great and reliable. But the newer drivetrains are horrible. Also, the interior is two Audi generations old, dating back to 2005 when the interior first debuted in the Audi A6. Which leads me to...
Audi A6: My God please avoid this car at all costs. I had a 2012 3.0T Supercharged. I loved it for the first few thousand miles, until it decided it didn't love me back nearly as much. I realized I could never get comfortable in the car's seats. They just aren't very good, and the driving position always felt a little odd. I realized the car handles poorly and the S-Line package is an absolute must...but the S-Line doesn't fix the awful electric steering which just allows the car to float on the highway. It never feels buttoned down. Worst of all, it's the lack of reliability within 12K miles:
-Excessive oil consumption
-Consumption corrected...and came right back
-Thermostat broken/No coolant flow, overheating engine
-Ventilation stopped sending heat (in the middle of the winter)
This kind of shit doesn't fly with me, so I didn't want to take the car with me when I moved to Florida. My dad regrets taking it off my hands (I wanted to lease trade it to someone else). So I ended up getting a 2012 Jaguar XF 5.0
-Jaguar XF: They don't make the 5.0 anymore, but I had a 3.0 Supercharged as a loaner car, and it's a great powertrain. Shockingly, the Jaguar XF without any sport trims and options handles very well. It is far better than the BMW 5-series and Audi A6, and not too behind the M37. I love the minimalist, yet highly sleek interior, and it's also got a lot of wow factor with the vents and the rotary knob opening up. Plus the 8-speed ZF shifts like a mother, which is awesome too. I have both the Jag XF and Infiniti M56S...and they're both sensational mid-sizers.
Drive both and see which you like more.
