Lias:
Over the course of 30+ years I can't think of a single person I know who's purchased a car from Turners and had a good experience. I concede that people are more likely to be vocal about a bad experience than a good one but still.
We've never had any issues with cars bought from them, often ex-fleet cars in good condition that have been properly maintained but have reasonably high km's, probably 5 or 6 over the last 30 years with out issues.
