My first memory of being in any car is of being in a Triumph Herald convertible. I grew up riding in a '66 MGB roadster. My first car was that same '66 MGB, which I drove in the '80s. And I had a couple of '77 MGBs concurrently. Now I have a '63 Triumph Herald 1200 convertible that I pretty much got accidentally, and a '66 MGB that is in much better condition than my first car.
Yes, British cars have their quirks. But POS? Not really. One of the things I liked about the old MGB as a teenager was that it was very nimble and had good acceleration. Plus it looked cool. My ‘new’ '66 MGB handles just as well. Sure, its 0-60 time isn’t as impressive now as when they were first made almost half a century ago, but it accelerates better than my Prius or Cherokee.
Problems? Well, British cars have their quirks. I’ve posted about a weird electrical problem, and the difficulty of erecting the top when it’s cold. Just quirks, that’s all. As long as you keep them in tune, they’ll run.
So for me, it’s nostalgia. I grew up with British cars, and drooled over a Norton at the local dealer’s when a 100cc Enduro was too big for me. ‘Unreliable and crappy’? The 'B was made for 18 years virtually unchanged. Can that be said about any Toyota? Besides, they look cool.
