Oxted GT seats in an S3

[WareMartin]

Hi All

I'm a brand new member based in East Herts and have just placed an order for a 420R kit. (I've a bit of experience of with Caterhams having raced R400s and joined a fabulous 7s club road trip around Europe roughly a decade ago). However, this is my first time on the other end of the spanner, so I'm looking forward to bugging you all when the build fails to go as planned... 

But before I even get that far: I like bucket seats, but my lovely wife has hips... The Oxted GT seats seem to be a good compromise, but it would be good to at least sit in one in situ before parting with the rather eye-watering amount of cash. Would anyone happen to have them installed in an S3 which i) they'd be happy to let me and the missus sit in (separately, obviously), and ii) are within a reasonable distance of Hertford/Stevenage?

Many thanks and looking forward to getting to know the community.

Martin
