"The council said every “mystery shopping” exercise on car repair and servicing businesses proved that people were getting a bad deal"

The implication of that is that a very high proportion of us are bad boys
With that sort of bad press we will always be on the losing side

Dont think any sort of scheme will erase that ,its basically down to money
A large proportion of the great motoring public detest spending money on vehicles,and will always complain of being ripped off

Joe Bloggs on the minimum wage gets a bill for £100 to get his banger through the test,all his lager and football moneys gone,so we are ripoff merchants
