this is one thing that scares me to bits.IF i get older and cannot work on my cars (or house for that matter ,anything!) who the hell will i have to trust to help me ?.there is no one i trust now as it is and if i (or anyone i know) gets anything done by a " tradesperson " or specialist etc there is always something wrong with it afterwards .i recently spent thousands on a bare metal respray that i only asked to be a flat and new topcoat but they have removed everything .this meant all my previous levelling and alignment of edges ,panel gaps etc and jow everyyhing is miles out .i had to totally dismantle the entire car and adjust ,shim etc to get it back to near what it was before !
we had daughters clutch done over christnas cos if was freezing and we were too busy .this came back with broken cable end held on with a cable tie and the front bumper fitted 1cm higher than the bonnet closing edge (yes 1cm !) i could go on !
basically what i mean is you cant trust a proffesional to do anywhere near as good a job as you can do yourself .maybee because of time restraints or just lack of care and attention .
