Yea, I know. They've come down in price quite a bit since I had one. I stole mine at $10k purchase price, but even then put another $500/mo into it to keep it running because I bought a bad specimen. All the things you said are true though, it's still a looker and will still rip along and surprise the heck out of a good number of more modern vehicles.
The things I would miss are some of the tech and the fuel mileage. Heads up display, adaptive suspension, 4 wheel steering, adaptive cruise, Android Auto and the rare occasion we use the 3rd row.
I really think I'm going to end up back in a pickup at some point. Trying to decide if I want to put any more cash in mods into the Q7 currently. Stage 2 tune with new pullies and a few maintenance items will be around $2,500. Get up to ~410-420hp or so. 325hp isn't bad with the 8spd, but it doesn't hit quite as hard as the SS did. New electric Silverado will be here in a year or so (hopefully), not sure if the juice is worth the squeeze on the Q7, or if I just keep riding it out and fixing broken stuff until then.
If I totalled the Q7 today, I would be looking for a new 3.0L AT4 on a dealership lot somewhere. I like my "point and shoot" SUV, but it doesn't work for me as well as my pickup did.
4 wheel steering is one of those things you really only need in a big vehicle IMO. The q7 being longer than the TBSS makes sense. I will say, the turning circle on the TBSS is really quite good. The turning circle on our Expedition however, is insane. I'm pretty sure it cuts a tighter u turn than the tbss, which has no problem with u turns, lol.
Adaptive suspension, meh. A good suspension tune is better than any adaptive system ive used outside of the horrifically expensive hydraulic ones. There's only so much shock adjustments can do, and imo, mag ride and similar shock only systems don't live up to the hype.
HUD and carplay can be added, I never use it on our cars, but I guess I don't interact with the phone a lot while driving. Some people swear by it and I've never gotten the value out of it. HUD on the other hand, I think everything should have a HUD. Being able.to see speed and temperatures in the vette is a huge bonus to me, and everything should have it.
3rd row... that one of those things you never know when you'll need. Trucks don't have 3rd rows either though!
Adaptive cruise... yeah, I feel that. I don't do a ton of highway in the SS because the expedition is the family car, but I use the adaptive cruise all the time. It's another great feature that I'd have a hard time buying a vehicle without.
I often flirt with the idea of a truck next. You look at what you get out of an f150 vs something like an Explorer st, and a loaded f150 is 6k more msrp but you get a LOT more from it. I just hated how floaty my f150 was with the fx4 package. If I had lowered it, I'd have probably liked it a lot more. I don't NEED a bed, but it's nice to have sometimes. And the coyote f150s get up to 600+ hp really easily with a rough or Whipple supercharger for 8 grand. Ecoboosts of course get to the 500s for just a tune, but I've yet to hear a good sounding ecoboost f150 exhaust.
I still want a hellcat Durango next, but if those become.cost prohibitive, a blower f150 could be an option. Or i guess a blower 6.2 silverado rst.
