My company supplies VW/Bentley/Lambo with lighting components and they are of top quality.
As is the case these days, they expect ultimate quality at a cheap price.
We do this by strategicaly buying our manufacturing equipment and making it in places like Czech and China.
Lambo and top marque suff is made in UK as margin to pay for skills required is there.
Car quality is much better these days than even 10 years ago, it is a very competitive market which drives this up
