In 10 years, the prices of old vehicles have increased by 400%, the passion has then turned into investment. In each episode, the presenter François Allain, passionate about cars for several years, buys an old car and calls on a pool of five mechanics to renovate it. Whoever makes the best offer wins the market. The objective is to restore the car to the state of the art at the most competitive price. The renovation will be punctuated by more or less problematic discoveries, and our specialists have only 15 days to settle all this. François Allain will then screen the car to validate its repair, before selling it at auction. Will our auto specialist succeed in repairing the car, meeting deadlines and making a profit during the auction?
