No, but they didn't extend into the 05E week of May.
Earliest known one is an 02D built car with a VIN that starts with 9N609xxx, it was on Ebay about 2 years ago. Has a lower VIN than the 2 "real" pacecars and all the festival cars, and it wasn't recorded as being at the track for the race.
Last known VIN depends on whos list you look at, but its well before the VINs for 05E built cars.
