Just to add to this thread dig, given I just read the whole topic...
I once had a loan clunker vehicle, loan vehicle from smash repairers who were repairing my near new Pug 206 GTi, this is after someone turned right across my path...

The loan car in question was a VR or VS Commodore Berlina... I was due to drive from Sydney to Orange the weekend after the accident occurred and this car evidently had low engine oil... Oil light was coming on at times e.g. when braking... Given I wanted to make it to Orange and such neglect pained me I did an engine oil and filter change on this car prior to heading off to Orange... It made it to Orange and back, but it was an adventure... It had a transmission slip whenever seeking to accelerate with vigour... I presented the receipts for engine oil and oil filter to the panel beater proprietor when the car was returned, he was quite shocked but thankful...
