I'm looking to get a car that would fall under the classification of a D or C sports Racer (DSR CSR). So far the only cars I can find that would accommodate a passenger are made by Radical (sr3, sr4, sr5, sr8) or ADR (adr3). Can anyone help me find any other cars out there that are similar to these, but at less of a premium? I've seen toyota world sports racers that are close to my cost, but all are driver seating only.

Any ideas anyone?
