Definitely, need to weigh the total package: creature comforts, performance, ease of use. I originally had a base model and aspired to have a GT1, figuring its creature comforts were the most appealing. Years later, when I drove a GT1 and a GT back to back, I realized I didn't want some of the GT1 features: I don't like sunroofs, the suspension settings weren't didn't seem to do much, and the sound system, while good, didn't justify paying more and having to accept the sunroof. The upgraded screens make an impression in the show room but the difference disappeared when driving, at least in my case.
Also, there are some things that aren't usually discussed in advertising or emphasized in reviews: how does the engine feel when you use it?
I'm going to use some mild exaggeration to try to explain what I mean: In my experience with mass market engines, when accelerating, V-8s go "gerrr", V-6s tend to go "vummm", and 4 cylinders tend to go "onggg". This can change with modern sound enhancers and some builders put in the time to engineer nicer voices via exhaust, intake resonators, etc. Some people won't notice or care. But I think it's important to pay attention to this before signing--the acceleration will hit you right away, but you may have to put that aside and pay specific attention to the character of the engine: cruise at 35, shift down to 3rd or second, feather the throttle up to 45, leave it in gear and listen to the engine when it coasts back down. It's not always easy to do, since it's easy to get caught up in the excitement of test driving.
For what it's worth, I did drive a
Sorento with the 2.5 and it is capable of pushing you into the
seat even in the larger vehicle. Objectively, it should be a great engine, but a buyer would be wise to pay attention to how it feels as well.
