The Sorrento is a small SUV. You drive a sports car. They are not alike.
You found this… surprising. Hm.
My husband has a 2005 Escape Hybrid, and he loves it. He gets about 26 mpg in winter (I think) and up to 29 mpg in summer - this is according to the digital readout thingie on the dash. (Our winters are hell on electric charges, hence the lower gas mileage in winter.)
It’s a nice vehicle. I agree it’s probably not as roomy as you’d like, though. I’d put two adults in the back seat for a while, no question, but would probably balk at 3 back there for a longer trip. Lots of cargo space, though, which is nice. Many other SUVs can handle tons of people, but fall down on the cargo room. It’s great to take 8 people somewhere with space for only 2 bags.
