Sure.
I never drove a 4Runner with KDSS except for the one I bought, but I would have bought one with or without KDSS. After having driven it, I am very happy it had the option. But if the question is being asked, and the OP doesn't know the difference are they really missing out? My only joy in...
Neither.. Why spend money on a car you'll only have for 2 years and 10k miles? It sounds like you don't necessarily need it or make much use of it. And if you know you're going to get rid of it before even buying it, seems pointless.
If you have to choose one, the SR5 will likely take the least...
