Today I think I agreed to buy a dealership demonstration car but I was not thinking straight because I have not seen it and didn’t realise I was signing my life away. I realised the same day I don’t want the car it’s not suitable. I emailed at 5.30 to cancel today. However now really stressed as I think I might have legally agreed to buy the car I have not even seen. Can I cancel on the same day surely I can. Also the finance agreement
