Ya... I can see the appeal. It wouldn’t add much capacity...but kids could turn and grab items during long drives...
This is another reason why I think Lexus could offer a 300 series that is an XL version... (or a 570XL) for people who want a legit off-road family hauler...AND LUGGAGE. Right now it’s either the Sequoia or a Suburban-based mister. No...it would not be ideal for crazy trails...but I think they’d Sell like hot cakes...especially to the Lexus folks who end up in a Cadillac XL because there's not much else to choose from in the large category of very-up-scale SUVs.
Porsche... Tiny.
Infinity... Blah.
Cadillac=glorified Suburban & marginal 4WD system.
Range Rover small too.
Hey Lexus... How about a super Cruiser or...just an extra foot or so back there for the families who actually need to bring clothing along?
