CV's should be taken with a pinch of salt. You can buy qualifications these days and pay an expert in wording CV's with business type hit words tailored towards the job etc. One can even buy good checkable references. Once you have weeded through the CV's and missing the true potential good employee who's CV did not come across as well written

what's you usual next step. Do you get them all in for an interview then to weed things down more, and how about putting them all to a few quick physical tests like a couple of hours in the workshop to see how they get on and whether you think they will fit in with the rest of the team.
I tell you what I am starting to see more now is rather than a job application asking for a CV is to provide the applicant with multiple choice type questions as to what one would do in a certain situation or put these in order of priority type questions. I suppose this is more character based rather than qualifications and work history which can be faked / blagged.
