Election Dilemma – vote or abstain?

I’m having problems with this Police and Crime Commissioners election.
Here in North Yorkshire it’s a 70 grand a year job – there’s no interview – no competencies or personality profiles are being checked – previous experience seems to be irrelevant – it’s just the popular vote that decides on the basis of what the candidates are saying about themselves.
Normally politicians (councillors and MPs) only share power with any number of other politicians. The PCCs are essentially on their own. All the power of the office is vested in one person.
So should I vote or abstain in the hope that low turn out will lead to a proper selection process in future.
I have never abstained from voting before – but I am in a genuine dilemma. I think the process is deeply flawed.
