Weber used to sell carb kits so you could toss the terrible SU carbs. And you used to be able to get conversion brackets so you could get rid of the stupid lever shocks. I think AC Delco sold electric kits to replace the terrible starters and generators. But that was a long time ago.
Fix those things and Brit sports cars weren’t so bad. I had an MG Midget briefly once years ago. A really fun little car in the mountains. Too bad Brit cars were such shyt. I could go on for an hour with horror stories.
You gotta spend big bucks to get a British car that’s worth damn......by that time you could get something made elsewhere that’s better quality and cheaper.
British sports cars were built to handle narrow, twisty, British roads, and were never meant be used on American highways. I had half a dozen Triumphs in the ‘60s, iincluding three Spitfires. They were all fun to drive with outstanding handling and superb gearboxes, when they weren’t in the shop, which was often. The biggest problem was the rod bearings. At our highway speeds they just would not last.
