I had the misfortune of doing spare parts for British cars and they were with out doubt the biggest heaps of #### that I have seen.
All the cars had prince of darkness electrics, out of date fuel systems ,oil leaks from every part and to top if of proven faulty parts were replaced with the exact same faulty parts.
Even the marque of Rolls Royce had just gone from SU carbys to K jectronis fuel injection ( volvo had the same system in the early 70's)
Back in 95 Discoverys had a R380 geabox this box was fitted to likes of Dolomites and whatever other crap Leyland pushed out.
The best news I got was when the boss ssaid we wont touch Leyland/Rover cars.
My dad back in the 70's had a Leyland Beaver prime mover damn thing near sent him broke but the Volvo and the Mercedes gave great service
British build quality I dont think so
