Referring to love/hate stuff on our current vehicles:
I can live without navigation too...never even did the initial setup in either of the Audis.
The Denali XL has all sorts of stuff I'll never use...OnStar and such.. and I *hate* roof racks on SUVs. I never put stuff on the roof and they'd look better/cleanup easier without the rails.
Speaking of the roofs, I can't remember the last time I opened a sunroof except to detail its channels, and I'd rather not have to mask off the edging every time I polish (the felt stuff on the Audis is fragile).
The new A8 project car has "anti-thermal" glass that blocks my V1...probably gonna change it (what an expense that'll be

) as I don't like any of the available remote radar detectors and I can't find the guy who used to make 'em out of V1s.
I've never needed headlight washers and they spray all over the car whenever I use the (windshield) washers at night. I can see the point, but they oughta be on a separate switch. Ditto for airbags and inertia switches for fuel pumps.
I wish they still offered switches to disable the ABS, at least I can still turn off the stability/traction control systems.
Gotta say that I've come to *really* like auto climate control. Our vehicles that don't have it would suit me better if they did...which always surprises me given how I used to dismiss it as unnecessary before I got used to it. Must be gettin' old
I'm always surprised how little I care about memory seats, but Accumulatorette and I don't change things all that much between the two of us. She'd say that heated seats are a must-have.
I'm a *big* fan of good headlights. Still gotta aim 'em right (and the factory settings are seldom optimal) and IMO not too many *are* aimed correctly. I've driven identical cars with/without them, and the difference is dramatic. At certain speeds it's a real safety issue to have good low *and* high-beams.
Why are foglights seldom adjustable and virtually *never* aimed right?!? Seems like they're just for show these days, and that's a shame. Rear foglights (the extra-bright tail light type) are great and oughta be standard...but I wonder if joe-average would think to turn it on. In my area too many people don't even turn on *any* lights unless it's pitch-black.
