Any particular vehicle can't have every possible option/feature, or they would all cost a ton more than they do. There are just things that manufactures skimp on to put out a different feature that the others don't have. Just like daytime running lights. GM has had them since 1996, but there are STILL other manufactures who don't put them on as standard equipment. This is just a reality of not being able to have every feature on every vehicle, hence...why there's competition, and so many vehicles to choose from. Basically you look at what your absolute NEEDS are, then narrow down from there. For me the list for when we bought the Enclave was this:
NEEDS (in NO particular order):
7 or 8 passenger vehicle
FWD
Cloth seats
Something stylish (which mini-vans are not)
Something affordable (less then $35K selling price)
Safe vehicle (ABS, air bags, stabilitrak, traction control, good crash results)
Automatic trans.
Air, cruise, power windows/locks, keyless remote
Remote start
WANTS:
Something GM (almost a need, but we could drive something non-GM, just have never done so)
Something built in MI (again, not that important, but something to sway us if possible)
Dual (tri-zone) climate
Power liftgate
8-passenger seating
Tow hitch (for hauling a bike rack)
THINGS I WANT IN OUR NEXT VEHICLE THAT THE ENCLAVE DOESN'T HAVE NOW:
Adaptive cruise control
Button for child lock doors on dash (like the Thetas have, Equinox, Terrain)
Push button start
LED tail lights (I know, the Acadia has them)
Parallel park assist, or whatever that's called....that would be cool, but don't need it.
No where on that list did I mention adjustable rear headrests. We almost never adjust our front ones, so this is really a non-issue with us.
(Nice posts, Quantum....that took some work....I don't think people will be spending the cash for front headrests to put in the rear, but still a nice thought just the same)
