To avoid possible destruction of the engine in F-cars the cam belt needs to be changed every 2-3 years....and yep, three years was nearly up.
This also means the engine has to come out as you cannot get access to the belts in situ. What amazed me is the subframe was designed to drop out and make the process as painless as possible....talk about the tail wagging the dog
Anyway, of possible interest to Top Gear fans is the toy with its engine out...
