Peter, I understand how you feel, but I don't think you will get anywhre writting to Honda UK. The dealer in Kettering is a franchise, so you are probably better finding out who the MD/Owner is and writting to them.
As you say, Bedford looked after you, so put Kettering down to a bad experience. They will lose out in the long run as word gets out!
I assure you, once you get your Civic, you won't be able to wipe the smile off you and your families faces and you won't give that sad wa**ker Rodger the Doger another thought! (Excuse my french
)
