It looks like the front wheel cover is missing which will effect the valve, but if you already own three C5's only you can be the judge of what you are happy to spend.
Cheers andy, i now have four c5's but I'm rubbish at judging their value as I only take any notice when there is one for sale locally.
Think it was a fair price and I'm happy as its the only one I've had that has come with working electrics so should be an easier project!
