I never buy new so last December I purchased a 2008 Shelby GT500 with under 2k miles. Should I wait and buy a low mileage 2010 in December of 2011 or modify my 2008 with FRPP performance package, FRPP handling package, axle-back exhaust, KR short throw shifter and 19" wheels? With the expectations of the 2011 Shelby being so high, I anticipate a lot of used 2010's on the market. Decisions, decisions.
