Time to upgrade to the larger vehicle with heavier suspension sir... but it will upgrade the price unfortunately :(

Might I suggest an Acura MDX or Lexus GX 460? The Acura will be more spacious than an Audi Q7 or Q8 with similar ride softness (unless you throw down for the Prestige Audi with Adaptive Suspension).

The Audi will be quieter and "smoother".

The MDX Tech Package is $59k and the Advanced is $67k
Audi Q7/Q8 will easily be mid $70-$80k

The larger vehicles will allow for easier entry/exit, more room for you and the fam, softer more plush seats, heavier suspension for softer/smoother ride, more insulation for less road/air noise and overall a more enjoyable experience.

I believe you'll find that better suited to us "Late Summer Chickens"...

Now - if you ever have specific questions or need more help on your next vehicle purchase, I am but a message away :)
