As above just gadging interest at the moment.
I organised a tour round both places about 7 years ago and everyone seemed to enjoy it.
I have been back in contact with Hethel and they only run the tours on wednesdays.
You get a guided tour round the working factory. Even get to see the design studios and trim shops etc. Then its off just down the road to classic team lotus. You get a talk by Clive Chapman and get a good tour of all their old race cars. You even get to do a F1 style wheel change on a type 72 or similar F1 car.
The cost of the day is £69 for both tours.
If there is enough interest, i will start a thread in events.
I had a date in mind for wednesday 9th october as i am on leave that week.
