If you like it and you have a use for it buy it. It's not really anything special, nor is it particularly 'classic ' in terms of quality, specification or age, but it does look to be in good condition.
It could make you a good commuter, pub bike or tow path warrior, even winter hack if that's what you want. I'd try and knock the price down a bit, but some prices are unrealistically high at the moment.
Whatever you decide to do enjoy, and welcome to Retrobike.
