Went a couple of years ago, there were a lot more vehicles than you described above. Lots of FIAT 500's though. A few Ducati's and Moto Guzzi's overrun with Lambrettas and Vespas along one of the side streets.
Bridgnorth is normally well attended, less bike and more car oriented but usually enough exotic cars to make the ride out and £5 to display worth it.
Raining at home this morning and the forecast for Bridgnorth isn’t any better from 10am onwards so it’s a no from me for this year.
Have a great day! I’ve asked the kids if they want to come if we drive there instead and they’re not interested
