Space & Practicality
Too close to call
If space & practicality matters most to you, this section won’t make the decision for you: they’re level. Don’t let space & practicality decide this one; look at the other sections instead.
Off-road & Towing
Too close to call
The off-road & towing section is even. Any gaps here are within the range you’d never notice. Both cover off-road & towing well enough that other priorities should break the tie.
