At about 3.40am the man was woken by noise at his home in Autumn Terrace, Burley, and ran into the street to see two white men turning his silver Audi TT around.
As he stood in the road the thieves drove at him at speed and hit him sending him over bonnet. Fortunately the man received only minor injuries.
The thieves had taken the keys to the vehicle, registration DN04JZM, when they broke in through a back door. An Apple laptop, mobile phone, and a wallet containing cash were also taken.
Anyone who witnessed the incident or has seen the vehicle since then is asked to contact Sergeant Liz Jennings of Operation Anvil at Belle Vue via 0845 6060606 or contact Crimestoppers, anonymously and in confidence, on 0800 555 111.
