Oversteer is cerainly a driver input commodity. You can defeat DTSC and with some good foot and wheel work the car will rotate. I admit though to having limited experience (had it less than 2 months).

300 Horsepower, 295 ft./lbs. @ 1,950 - 5,250 rpm
2.5-Liter, 5-Cylinder Turbocharger with Aluminum Cylinder Head / Block and Dual Wide Range Continuously Variable Valve Timing on Intake and Exhaust Camshafts

Climate Package: Heated Front Seats, Rainsensor
A recent Dyno:
Vehicle: 2005 S60R 6MT ~14,500 miles
Mods: Completely stock
Dyno: Dynojet 2wd dyno
Conditions: 75+% humidity ~65deg F, 2wd mode (with fuse pulled), Advanced 4-C setting. No changes made to the DSTC setting
All dynos are SAE corrected with 5 - 10 minutes of cooling between each run. Unfortunately the fans they used to 'simulate' driving air flow was pathetic, to say the least.
Dyno Run #1:
Max HP 254.56
Max TQ 281.00

Run two hit 287TQ at the wheels...ALL 4!
Good mods ca be found at iPD, VP Tuning and Evolve.
As for comfort, I can't speak highly enough! The fit and finish of the interior is amazing. The 4C adn selectable suspension are really cool! The front is comfortable for any size person. The back seats are not too much bigger than a Contour.
Performance wise, it's hard to beat for the price when you look at the total package. You could get the fun factor from a STi or EVO8, but they would lack the refinement. An S4 or M3 would be significantly more, but also post superior performance to go with the quality.
I will always have a Volvo. That's the best endorsement I can give.
