Test drove several CPO's to include Lexus, BMW, Mercedes and Acura's and didn't find any to be as comfortable, safe and as fun to drive as the S80 V-8 AWD. While it may not be as sporty as a 5 Series or as luxurious as an E-Class or Lexus, it is the best total package. The AWD has proven itself to be a winner during this harsh Iowa winter. I've never felt as safe and secure driving through snow as I do in the S-80. Added two 9 inch DVD screens to the headrests so we can use it instead of the Minivan in bad weather. Best part- wife didn't blink at the price because she loved the S-60 we had previously. Personally I think the V-8 is the way to go, but I'm sure the T-6 is fine as well.
Great CPO program, safe and secure ride, AWD is tremendous, upgraded stereo rocks. Had the after market Garmin GPS installed at the dealer and I love it.
As always gas mileage could be better, but I opted for the V-8 so no real complaints.
