Piaggio Vespa Episode: 2.07
dvla info for YWV 140 are: Date of Liability 01 09 2008 Date of First Registration 07 09 1993 Year of Manufacture 1961 Cylinder Capacity (cc) 125CC Registered as "Vespa (douglas)" but the Piaggio logo is visible. Note the year, too recent for the episode set in the 50s, but as the Vespa is taken from the Tardis and that it is explicitly said in the episode that this vehicle was too recent, I guess it is not a goof (except if they just wanted to make like if it was a 60s/70s Vespa).
The Vespa hasn't changed much over the years of production, that why they used a recent model

From "Aliens of London" (Ep. 1.04):
Triumph Scrambler Episode: 7.15
Something from "Day of the Doctor", as no one is doing Dr Who. No idea how to list it properly, 240 = 7.15 ?? http://en.wikipedia.org/wiki/List_of_Doctor_Who_serials Scrambler. It is a special episode, so I am not sure... on IMDB it is in the "unknown" section. We could list the special episodes as "S." followed by a number, or as 7.15 indeed, or as 8.00 in case it is the start of a new season. Is this plate identifiable? Most if it can be made out. WP62LWT = Not found. Previously used in (7.06). The Scrambler was first introduced in 2006.
Can't trace WP62LWT, but nearby combinations are genuine - eg WP62LWR = WHITE 2013 BMW 120D M SPORT AUTO 5 DOOR HATCHBACK
