Just got into this vehicle after much research (1 yr). It came down to S60 vs. TL. S60 won because of cabin comfort (incredible!), fold flat rear seats, 8-way passenger seating, hand-brake location (driver side), Regular fuel & Trunk capacity. Overall I'm very satisfied with the ride. Makes you feel like driving all day... It's been 14 years since I've driven a new car (came from a 93 Integra which is the best car in the world!!!). It's going to take some time getting use to all this new technology. Will keep you posted...
So far... Front seats/comfort, home link, headlights (they move), geartronic shift and fold flat rear seats.
Turning ratio. Better flexibility with Satellite radio. Even if you upgrade to HU 850 with Sat prep. its another chunk of change to get Sat.
