I was trying to sell my Aston Martin Vantage V8 4.7 through a garage who offered a sale or return deal, taking a commission if the vehicle was sold. Five weeks and 300 miles later, only two prospective buyers had test driven the vehicle. On the same day that the car was due to be sold, I was phoned to say that the engine of my car had 'blown up'. They said it was most likely bottom end or top end or valve problem causing a severe knocking noise. Listening to the video most experts believe the engine is toast. Do I have any possibility of recouping the estimated £13,000 for a reconditioned engine? The only contract we had was a message stating that they would try to sell the vehicle and take a commission if they did.
