Mercedes is offering a new and upgraded version of the SL-Class R231. The June 2013 production series come with enhanced standard equipment and key exterior appointments, in two SL350 and SL500 variants with AMG sport packs.

Including the AMG kit, the new SL comes with £6,625 worth of extra equipment. You get new colors, including one non-metallic paint and five metallic paints, including new Polar White as standard, with the cost option of two addition colours, including new Hyacinth Red (£690), Black Leather interior with Bengal Red or Porcelain nappa leather options (£710), and Light Brushed Aluminium trims, with Black Ash Wood available as a £345 option.

The AMG Sport Package includes 19” AMG five-spoke alloy wheels; sports suspension lowered by 10mm, with revised damper settings; AMG body styling for side skirts and front and rear aprons; a body-coloured boot lip; upgraded braking system (SL 350 only) with perforated rear brake disks; and grey brake calipers with ‘Mercedes-Benz’ lettering.

The only changes made to the SL63 AMG version is the addition of electric panoramic glass sunroof and Parktronic with Active Park Assist. The SL65 remains intact.

The new-spec SL350 is priced from £69,960, the SL500 AMG Sport from £79,970, and the SL63 from £110,785.
