Look at what the motors have internally. The Shelby can handle a ton of power and have a blower from the factory. The 2011 is questionable due to their rods and pistons. Plus suspension and brake upgrades.
Plus the Shelby will hold value better due to their limited production numbers.
Normally you are like Yoda….very wise you are….but I have to disagree.
The 07-09’s are going to take a hit on price due to the 2011’s (and 2010’s to an extent). Ford really hit a homerun with the interior in 2010 and improved the Shelby’s dynamics in 2011. If you read the reviews, the difference is night and day.
My preference would be
1. 2010+ GT500
2. 2011 5.0L
3. 2007-2009 GT500
Why did I put the 2011 5.0L ahead of the 07-09 GT500? The interior is vastly improved, has more standard content (and better options), it’s much lighter and dynamically more balanced. The 5.0L also responds well to mods, but it’s not going to beat the GT500’s blown motor in mod-a-bility.
