According to a 2012 study, about 40% of the components (by value) in a British-made car are sourced domestically.
By contrast, in Germany and France about 60% of parts come from the domestic supply chain.
But taking into account components, the automotive sector as a whole is still a large net...
All well and good but the UK needs to balance it's economy with some good old fashioned making stuff. The benefits of this, and the associated "proper" jobs are wide spead
Not true. The UK assembles a lot of cars but it's stretching the imagination/truth to say they're manufactured in the UK. Interesting that you mention Italy, as they apparently actually manufacture many parts for UK cars
You are being very very disingenuous with your post here.
