I DD mine too. Kids to school, off to work, errands to Home Despot. I wanted a fun/exciting DD that was practical and the GCSRT8 was it.
Here's a list of a vehicles I test drove before buying the GCSRT8:
EVO --> too boy racer
370Z --> very nice, fast but too small/no backseat, not really my style (ricer)
Camaro SS --> nice, fast but too small backseat and wife disliked severely
Mustang GT --> nice, quick but quite there for me -- really want a Shelby GT500 but that's not a DD.
CTS-V --> budget buster! but WOW.
SRT8 Challenger --> very nice, quick too but the interior was bland besides I get the same performance from my GCSRT8 (or better!).
Audi S5 --> very nice, slower than others and smallish backseat, great styling. Wife loved it so I figure she can get it once it's time
For the price I paid for my GCSRT8, there aren't many challengers to it's capabilities, practicality and sheer FUN. Like someone said, smiles per gallon factor is priceless.
