I should have been more specific I guess. What I meant was Mechanical Specifications and Convenience abilities. I do know a SUV would have to meet or exceed several criteria to be deemed "Truly Purposeful".

Indeed, On-Road ride quality and Luxury features would be a mute point in such a list.

It would have to be:

(A) Powerful and Reliable
(B) Able to perform at least Intermediate Off-Roading or Better
(C) Able to carry a suitable amount of Passengers* and or Cargo/Luggage*
*(More than what a standard family Sedan is able to accommodate)
(D) Have a high towing capacity*
*(This excludes car-based or Crossover SUVs)
(E) Ergonomically friendly
(F) Excellent Safety Record
