I hear what you say but it all comes down to price
Does anyone get their car repaired these days, after all most accidents are write offs so just get 3rd party insurance cover
I can buy most car parts from overseas with the only worry being cost of delivery
EG
1999 Subaru Forester
80 000kms @ us$3 800 (Plus delivery)
So at that price you can afford to write it off early, plus as they are sold in Australia most of the parts would be available here and their service and repair requirements are also well known here
So it has to be buyer beware therefore IMHO it would provide a opportunity which is now lacking
