For close racing the Silhouettes are great fun. I think they're somewhat underrated, probably because their rep suffers for being the class most used on crash-fest public servers. I think the same can be said for the Aquila, which again is a great car for close racing in the right crowd. The Judd is good for racing alone if you want a balls-to-the-wall experience, and the FR Junior is good for practicing basic technique.
