This law empowers the judiciary to punish companies or individuals who make false claims about the products or services that they sell.Sorry you are wrong. Trade description covers people and businesses trading as a business or trade, hence the name, not private sales. I suspect this is a private sale from classified ads between two individuals.
Best option is the seller accepts to pay for some repairs.
If its in an ad and its incorrect or misleading single or business then it applies to you. http://www.legislation.gov.uk/ukpga/1968/29 This law applies to all.
