Paula Cassidy: He drives a Ferrari. It's Red.
Tony DiNozzo: Like Magnum.
This is reference to the long-running series Magnum, P.I. about Hawaii-based private detective Thomas Magnum. The Ferrari in question belonged to his employer, Robin Masters, but he was allowed to use it the majority of the time, provided Higgins hadn't taken the keys for some transgression Magnum had committed. The show was another Bellisario production.
