Belling Ceramic Hob Double Oven Cooker ?

I bought this Belling cooker/double oven at the begining of this year, it was purchased off Gumtree as I had planned to move into an unfurnished flat, however as it turns out, I dont need a cooker although the flat is classed unfurnished. The Seller had only bought it brand new a few months prior to me buying it, the only reason he was selling it on was that he was moving in with his girlfriend and they didnt need two cookers. The Cooker is in immaculate condition as you can see in the photographs, it was and still is a bargain at this price. I paid the seller 300 for the cooker and I am looking to get this amount back seeing as I have not used it, only protected it and stored it in my bed room. I would possibly negotiate on the price, depending on the offer. I am disabled and only have a small car so I can not deliver the cooker/oven, it would need to be collected. Thank you for looking, Any questions feel free to ask! :-)
