A £30,000 2004 Chesil 356 Speedster is likely to be written off after it was knocked into a canal by a passing van, The Metro has reported.
The Porsche replica was parked outside AutoVero Luxury and Classic Cars in Islington, north London.
The garage owner described hearing a “smashing noise”, which alerted him that something was wrong.
AutoVero’s owner and director Kalvin Cauldwell said: “It is an item of stock.
“It is now in the canal with lots of people scratching their heads thinking ‘how are they going to get that out?’
“I was with a mechanic dealing with a Ferrari and I heard a smashing noise, then I was looking around and it was the canal.”
Mr Cauldwell said a delivery driver somehow made contact with the car which was in a car park at the back of the building.
He added: “He managed to slide past a Mercedes that was there as well.
“It could have been much worse, definitely.”
Mr Cauldwell, said he expects the car to be a “total loss”.
