I hear you Gilly!
I never try to sell cars that need to be fixed.
It's bad for business!...
But if you really think about it, the worse case scenario in the realm of the unforseen is possible in any circumstance, even with a new car.
The only difference is, that the book value drops off when a car leaves the lot...
whereas if you buy at wholesale, you have gained value when the vehicle leaves the lot.
Why?... you've bought the car way under the ever decreasing book value at the time of purchase.
This can be a good buffer toward the worse case scenario...
at a cheaper cost overall...
I've seen warrantee costs that far exceed the cost of repairs during the length of it's contract.
As for jack of all?... I guess I have varied interests!
I may not know everything... but I know a little about alot of things...
