Hi ALL,
I would not want to stop DIY repairs, probably everyone here cut there teeth doing DIY on there own cars. As pointed out there are many DIY mechanics who are more competent than the cowboys running back street garages. I had a qualified technician sent to me for re training due to overtightening of the rear wheel bearings. This practice was widesperead throughout his dealership, he was the unlucky one, but obviously lucky no one was hurt. Maybe certain tasks on motor vehicles should be checked by competent people as is the case with house electrical wiring.
Just my thoughts.
James
