Still think it's a bit of an ask at that price, especially with no extras.
You need to aim around the £15-16k mark IMO - however last time I mentioned this my post was removed.
I'm not trying to be a git mate, but with the way the Market is at the moment, such cars aren't selling very well. I dropped from £18k down to £17k and even then I wasn't getting many views, even though the car had some extras on it!
Either keep the car as it is a collectors item after all, or be prepared to drop the price if you still continue to get no interest. Personally, if you don't really need the money, and it seems like you don't if you are prepared to swap for a R32, I would just keep the Ed30.
