Anything in the 12.0- 12.5 is defiantly respectable for a DD. Anything in the 11's for a DD is fast. The way I see it, if you were to take a look at the majority of the cars on the road each day, like your Accords, Carollas, SUV's, family sedans and sport coups and then compare them to a WRX running 12.30's, you would have a fast car. Sure there are other factory cars that could out run that, and I'm sure everyone knows a guy with a faster car. but in the grand scheme I still believe mid 12's to be respectable.
