Chell's is still there - but, not a Honda agent these days.
In my time, Phil Bright was in Browning Street, I had bike MOTs done there, back when the brakes were tested by pulling the bike with a winch, rather than the rolling road device. The old boy who did the tests was reluctant to do mine once, because he didn't have an assistant to operate the brakes as he wound the winch up - so, I volunteered to do it for him but, "We're not allowed to let the owner do it - some people have to use both hands and still have the veins standing out on their forehead!" I persuaded him that I would be 'reasonable' and we circumvented the rules.
Some of Phil Bright's collection used to be on display in the showrooms along Astonfields Road, where the Kia, FIAT, Renault and Dacia places are now, but I don't see them via Street View now. But, if you go back in time, you can see some -
