When I describe a car as fully sorted, here's what I mean.
All cars, even producton cars, have minor assembly issues that rear their heads soon after they hit the road and "adjustment" issues that must be delt with. A new engine for example, will require a break-in period that will include oil changes and usually a valve adjustment within the first few miles. Cables stretch (clutch and throttle) an must be adjusted. As the body of the car sits on the suspension, it settles and the alignment may need to be done again. If a motor is going to fail, it usually does so pretty early in the game.
Parts that are defective out of the box rear their heads in the first few thousand miles (including engines). As many of the parts for our cars are not OEM, that means more of them may need replaced as they are not high quality German parts. Example - I went through three flasher units in the first 1000 or so miles. One came with the harness (crap), one I bought (crap) then I bought a good one and have not changed it since.
After the first few thousand miles, everything settles in. The flaky bits have been sorted, the valve adjustments done, motors broken in, alignment finalized etc.
At that point, the car becomes a reliable little "driver." It is then sorted. My "sorted" point arrives when I can confidently drive the kids to school, dentist appointents and haul ice cream in the summer. It must start under all conditions, never overheat and under no conditions quit running. Everything "works." When I feel that confident, the car is trustworthy - sorted.
