In general, the cars we prefer are the performance-minded versions of pedestrian models. We'd rather have an R32 than a standard Rabbit and we'd rather have a Mazdaspeed3 than a Mazda3 sedan. But this doesn't mean that every souped-up model is a lock. Does anyone really need or want a crew cab Dodge Ram SRT-10? Does the Mercedes Vito van really need a Sport X model? We love the Turbo Dodge Caravan, smart move Chrysler. Though we're tempted to ask Lexus what they were thinking with the Lexus IS-F. Does anyone really want that car?
