I think prices are a little over inflated at the moment and not realistic, my mc28 se sold for just over £3.3k last night. Lots have also been for sale and not that many have been meeting reserve or selling.

Maybe it's a result of the market being flooded recently by lots of new imports and the current plentiful supply.

It looks a excellent condition and a very low milleage rare example so I would imagine it would be advertised at around £5k by some places but only realistically achieve around £4k, but that's just my opinion.
