The problem with records lists is this... the McLaren held the record for a road-legal "production" car for 11 years. But it wasn't on sale for all of those 11 years, so you have a few years in between where you have no data on the fastest production car then in production... not unless you dig.
And "production" is such a vague term... If you produce it, and someone buys it... is that not "production"? That would open up a whole new kettle of fish when considering speed records. The Callaway Sledgehammer was faster than the F1, but was a "production" of one... though Callaway was willing to sell further examples for an eye-watering $400,000.
Also note... things change if we're considering "stock" versus "modified"... "modified" being the excuse some people use to disqualify such top speed record holders as the Callaway Sledgehammer... the McLaren F1 that held the record for so long wasn't in completely stock trim. In completely stock trim, the F1 can only do 230 mph.
