I can say otherwise
- My main dealer has fit Hills bearings and a couple of other minor non-standard parts when I have asked them to. My point was the non-OEM part was superior, they agreed and fit it in place of the OEM part. That was with a service manager who has now moved on but I'm assuming they still will if I ask them to.
The guy at my main dealer who did my last engine out there won Ferrari technician of the year in Maranello shortly before - it's a worldwide annual competition in Italy for Ferrari mechanics where they are tested on all cars from the latest modern cars right back to the classics. While you can't be sure who you'll get working on your car at a main dealer I was pretty sure he knew what he was doing. The guy's name is Dean Pallett and last I heard he had moved off the shop floor and was now the service manager so should oversee work done if it's by a technician with less experience on older cars. I'm not sure that's very different to one of the bigger indies who have a mix of younger guys with less experience but guys with more experience overseeing them.
In fact here's an article about him wining the award -

Anyway, I think there's positives and negatives across the indies and main dealer network. I'll be honest, I used the indie I used because I liked the people. But they have to offer something the main dealers can't if they want to survive. At the point they end up being more expensive and don't offer a better service they cease to be a sensible option.
From what I've seen Bell Sport and Classic do offer something above your average main dealer. Were this for something a bit more involved than an annual (plus a couple of items missed off the last major) I might well go that route. But I'll be honest, given the service being done this time, I'd do it myself if it wasn't for service history. Taking into consideration shipping cost, using Bell for this annual rather than my main dealer just down the road will add £500 to the bill. Come time for the next engine out belt change I'll look seriously into using them though - they look like they've got a great setup there.
