What made you choose E63 over Panamera Turbo , RS7 or M5?
unless youre gonna drive in a foot of snow, and then even AWD wont help.
im in edmotnon and i have a RWD cls63, after i put winter tires on it(Michelin pilot alpin) the thing plows through snow like its an AWD.
i literally look forward to going out for a drive after it snows. the confidence is that high in these tires.
Porsche: Really like them and will own a 911 Turbo someday when I can live with a two seater. Possibly my next car. Panamera styling sucks.
Audi: Seems over priced, long distance to the dealer, RS7 styling isn't for me.
BMW: Also nice cars and I've owned a few. Had a bad experience with my local dealer and so will never own another.
it has way more presence on the road than an e63 if you asked me - lower, wider, wider wheels, etc. it actually looks almost supercar-ish...!
of course im referring only to a turbo or turbo s, not the base panamera.
the e63 has always struck me as an "old mans" car... especially the interior.. although the new exterior has grown on me... i think it looks really good, now that its on its way out... lol. but it needs a drop and spacers..
the interior of the panamera on the other had isnt for me. all those buttons reminds me of an airplane cockpit.
Get good winter tires and no issues at all, on anything short of a foot of snow, then just get a tractor

Audi -- Audi steering. Quattro. Enough said.
Panamera -- the styling, unfortunately, is butt ugly. Not a fan of the long transmission console with a million buttons, either. Car is even heavier than the E63. PDK can't get rid of the power/weight ratio.
BMW -- M5 drives great, however had too many issues with a previous Bimmer so hesitant to go back. Also, I have always preferred the power delivery and sound of the AMG engines.
E63S - Great looks, awesome power delivery. Some issues like trans inconsistency and Eco button, plus 33/67 torque split but not deal breakers at least IMO. Just have to drive the car differently to compensate. Hell, no car is perfect.
