What about English cars Milo?
TBH, there aren't many fully British car manufacturers left.And most of the ones that have gone were pretty poor.
But of those made in the UK the best ones are the luxury or higher end models and sports cars.
Rover,Range Rover,Jaguar,Aston Martin,Lagonda,Bentley and Rolls.
Then there are the sports cars, many no longer made,Mclaren,Lotus,MG,Morgan,Caterham,TVR,Marcos,Austin Healy and AC.
One of my favourite sports cars was the AC Cobra( Though it had an American engine)
A totally impractical car for day to day use but great fun to drive.
The sixties Mini Cooper S was fun to drive too, almost like driving a Go Kart!
