That heavy '10 SHO you're talking about starts around $35K after rebate which is only a couple grand more than a popularly equipped '10 Mustang GT Premium. And the SHO runs mid 13's @ 103 mph in the 1/4 mile, which is quicker than every "classic" 5.0L Fox-Bodied Mustang as delivered from the factory!
Corrected I removed "most"
