What event did I see and was anyone in involved?

[D4VE 3LL]

Basically I work part-time at a garden centre called Webbs of Wychbold, Droitwich near Worcester and as I arrived for work yesterday morning the car park was full of classic cars such as AC Cobras, Morgans, Jaguars, TVR Chimeras and Griffiths, old Porsche Carreras, Caymans, quite a few Lotus Elans (about 10 years old) etc. Around 50 cars I'd say. They then put logos on there car (the sort of classic Monte Carlo Rally style ones) saying "Classic and Vintage Rally" or something similar on a green background. They then all left at different intervals by stopwatch and headed towards the M5 motorway. Im just wondering if anyone was involved, where it went to etc...
