A Caterham Seven is the classic choice for someone wanting to build a car completely from boxes and bags full of parts, making sure that you've assembled every single nut and bolt. Halfords have partnered with Caterham to service their Seven racing cars, and it's made me want one of these beauties in my life! But what would you personally go for? A full restoration of a classic? Or building a Seven to go racing? Tell me in the comments!
