Hi I have a C5 for sale, it's currently on EBay (for £299) so can be seen on there, it's in good condition with original tyres, wheel trims and centre caps, it has been modified, I have fitted a new car battery and new cut out switch, also supplied is a new battery charger, it comes with a spare electric motor, led pod, pedals and padded handlebar cover, everything works, it has been used obviously so does have signs of wear but is in good condition, I'm asking £250 for it and I am located in sunny Torquay in Devon, you can email me at baydisco@gmail.com
Here's the Ebay advert, looks like a nice c5;
