AzGeo,
I think this is a really good idea in theory but. . .
As a big privacy advocate, I'm not convinced everyone wants their real name splashed on the internet (whether they're considered great by us or not.) A quick check of the handles in use on most forums will back that up.
A request was made to Cadillac at least once that I know of for a listing of XLR techs in the US. This went unanswered. Either they don't know, or as a company policy, don't release employees names, which is pretty standard.
However . . . I don't know of a dealership that isn't listed on the internet in one form or another. I think it would be just as beneficial to get owner's opinions of the good dealerships (with great techs) and list those instead.
Just my .02,
CC
