First of all, just for the record, I walked UP the steps in the Lambeth North station, turned around, and took the photo!
Now the car. Marie came through again!
It's a 1934 Standard 10, a brand I had never heard of but apparently quite popular in its day. Apart from info about cylinders and struts and other incomprehensible stuff, I found out it cost £185 new, and looked something like this.
Or, if you want one for your wedding or other fancy transportation needs (as long as they occur in the vicinity of Swindon UK because they don't like to take it too far afield ), you can contact Functioncars.uk.co and reserve their 1934 Standard 10 car, which looks like this.
Oh, and their website says it does come with a sunroof, wire wheels and a "fabulous sounding 'ooga' horn that commands everyone's attention"!
Who wants to go for a ride?
