The SL65 AMG had an original msrp of just under $200k. Since the SL65 has the full AMG treatment-the SL600 doesn't-it gets a more aggressive body kit that includes a front bumper with a wider mouth that accommodates larger intercoolers. There is also a rich, deep-throated free-flowing exhaust that actually sounds like a turbocharged V-12. Further tweaks ditch the SL600's 18-inch wheels and add larger two-piece 19-inch wheels filled by 15.4-inch rotors clamped by enormous eight-piston calipers up front and 14.2-inch rotors with four-piston calipers doing the squeezing in back.
