A stolen $300,000 Italian sports car has been found at the back of a service station in Melbourne’s western suburbs.

The silver 2012 model GTS Maserati had been parked at the Blue Planet Carwash on City Road about 11am on Monday before thieves sped off with it.

A Victoria Police spokeswoman said it was believed the keys were left in the car at the time it was taken.

The vehicle was eventually found at a service station on Fitzgerald Road in Laverton North, reportedly in good condition.
