For a base model C2, depending on the year and stuff...thats about right. There are tons of Carerras (all of them 911's, except the Carrera GT, but they are also given a numerical nomenclature such as 964, 993, 996, 997 to designate different years/body styles). Turbos are the fast ones, C2S and C4S next fastest, then C4, and finally "base" C2's are the slowest.
