HELP! Need to Hire a classic American car for a prom!!

[Rockettvr]

Hi all
Title says it all really. Sons prom is in a couple of weeks (16 July) and he and a couple of his friends would like to turn up in style in a classic yank motor. However I'm having real trouble finding a company to hire from. Tried all the local ones I could find on the internet but none are able (willing?) to help they only seem to do weddings.
We are in Essex very close to the dartford crossing and the prom is only around 5-6 miles from home.
Any suggestions as to a company that may be able to help ? Don't mind if it comes chauffeur driven or self drive.
Thanks to all
Ron

A family friend in Romford has a 1956 Cadillac Deville 4 door. If that's the sort of thing you are after let me know via PM and I'll pass on his telephone number.
