Overview: Wheeler Dealers returns - to the delight of Britain's motoring fans - as the team takes on the challenge of a lifetime: renovating a Triumph Spitfire. Mikes hunts down a Triumph Spitfire using the internet. First, he looks at a GTR, but the car is in too early a state of restoration. He then moves onto a 29 years old Mark IV in British Racing Green. On the test drive, Mike hears a whining in the differential and has concerns for the suspension.
