I did some test & survey for E39 530i & Volvo S60 T5.
I love the Volvo because of POWER (260hp, compared to E39 530i 231hp using RON98, local RON97 would give about 5 horses less?)
Safety, no doubt the safest car.
Alright and that's it.
E39 530i
Engine ROAR! M54B30 once best 3.0L engine in the world.
FR driving experience. S60 T5 is a big horsepower FF, lots of torque steer. It won't handle as good as E39 on the highway. My Sonata NF 2.4 with 160+hp is already torque steering on the highway corner, I know S60 is way better car than a Sonata NF but it's still a FF.
Sheer Driving Pleasure, what can I say more.
And I personally love the angel eyes on the E39. Coupled with XENON lights, night driving on the highway, all the cars would automatic clear the path on the fast lane
