I drive a '06 XC90... I chose the V5 over the V8 b/c most of my driving is just in my little 10km radius and I don't need the extra pep. I love it. It's pretty good on gas (but it's still a guzzling SUV), muuuch better than my other SUVs, most GMC - I've driven about 5 Jimmys and Envoys over the yrs. They're ridic. The V5 is a lot better than the V8 IMO. I have actually watched the needle move in those!
