Price of 2008 S63
Would suggest test-drive of S600 vs S63....similar pricing...but for largely straight-line driving/commuting, prob would opt for 600, not 63....
600 effortlessly delivers vastly superior mid-range tq; has far more elegantly finished interior....
63's strengths are far cooler exterior body/wheels/exhaust tips/brakes; sharper steering, chassis....some of best brakes on planet today...a rather charismatic exhaust note....but 63 suffers from an abysmally plasticky interior that belongs in an E/ML, not a $150K car....
If live in region requiring winter tires/wheels, prob easier to find competent winter tires/wheels that work vs 600's relatively modest-sized (but adequate) brakes, as opposed to 63's notably larger brakes....
