This month, Discovery Real Time hits vehicle velocity with a brand new fourth series of the immensely popular turbo show, Wheeler Dealers. Expert car trader Mike Brewer and renowned motor specialist Edd China will be working together to keep six impressive cars, including a Porsche 911 Targa and Alfa Romeo Spider Veloce, from the crusher.

With just £4000 to spend on each vehicle and only a week to complete the renovation work, it's a tough challenge for Mike and Edd to transform these tired motors into dream machines.

Carrying out the essential work in three stages, Mike will source a vehicle in need of repair through the internet, a specialised club, small ad or car auction.

Sharing practical advice as he goes, Mike will lead viewers through the minefield of second-hand car buying and pass on tips and tricks of the trade for choosing the right motor. Master mechanic Edd will then use his expertise to look over the engine and bodywork and assess the work ahead of them, ensuring each project is achievable and falls within budget.

With the priorities established Mike, Edd and the crew will get down to restoring, revamping and in some cases, remodelling the vehicle to make it roadworthy again and return it to its former prestige condition.

Whilst the work is being carried out, Edd will not only offer practical guidelines and advice on the techniques he is using, but will also ensure that the repair equipment is easily available and will give an accurate assessment of costs involved.

Each of the cars will receive at least four major repair jobs as well as a multitude of smaller tidy-ups, and problems will cover all elements of key rebuilding, such as electrical, structural, mechanical and cosmetic.
