Last I heard Walton owns the one and only 412 MI Ferrari, a car whose engine began life in the 335S in which Fon de Portago, his co-driver and a number of spectators were killed in the last "real" Mille Miglia. He also owns a gorgeous 250LM and a Dino-engined sports racer (not sure of the I.D. on that one, but along the lines of a 246SP). Until last year he also owned one of the Corvette Grand Sports (the Sunoco-liveried roadster). Also owns the first Scarab sports racer (the one Lance Reventlow had briefly converted for street use), a whole bunch of Maseratis, and Lord knows what else.
I was disappointed in the Monterey coverage, personally. Very little on-track action, especially in the "feature" race of the weekend (the one involving the GT40s), which was given all of about three minutes of coverage. There are a lot of race groups at Monterey but it was a two-hour program, after all...
