While I LOVE my Enclaves. If I was on a strict budget and not wanting to spend a ton, but need a vehicle capable of hauling up to 7 people... I'd get a Grand Caravan or Town & Country, or Pacifica minivan. The tires will be much cheaper than any you can put on a 7 passenger SUV. An 11 year old SUV will likely need things like tires, brakes, wipers, rotors, etc. The cheapest I've gotten our tires for was $800 for Hankooks and they sucked. We slid and peeled out anytime it rained. Or even just taking off from a stop light.
The minivans come with their own issues but are easier to work on, parts tend to be cheaper, etc. We had one prior to our '12 Acadia. It didn't require a 3 ton jack, or 3 ton rated ramps, etc. It was just easier all around. My husband misses the ease of that and our 2012 Cruze we got rid of a year ago. Plus with a Grand Caravan,Town and County, Pacifica you'll likely get Stow N Go and that is amazing to have if you're hauling a bunch of kids or pets around.
Sorry if you're not getting the answers your really wanted. But for us, our most cost effective vehicles that didn't have bumper to bumper warranty, were our 2012 Cruze and our Grand Caravan. We've had Toyotas, Mazdas, Jeeps, Dodges, GMC, GMs, Chevy's, Buicks, and Honda's, those 2 we're still the easiest to work on and find parts for.
In fact, I was looking at a '22 Pacifica or a '22 Grand Cherokee L if I didn't get my '22 Avenir.
