Our answer to How often will quality scores of 10/10 be found in an Adwords account?
This very much depends on the types of keywords you have in your account. It is very to difficult to get 10/10 on a term for which your brand is not uniquely relevant for. I.e. on the term 'cars' there are a large number of potentially relevant marketers so it is rare that one of those marketers will distinguish themselves enough from a user engagement (CTR) standpoint to garner a 10.
The terms for which your brand would be uniquely capable of delivering a relevant experience would be for branded terms as well as for niche offerings, where you are one of maybe a handful of firms who could deliver on the searcher request. If these terms represent the bulk of your portfolio, I think it is realistic to expect that a majority of your keywords would run at a 10/10.
