Looking to buy another vehicle, I checked on several of those 'low mileage' cars a few years back, all that I looked at had been one-owners, but the problem was, they wanted near-new prices.
For a few bucks more I ordered a new car from the dealership that I then knew was 1.) 'no' miles 2.) full factory warranty 3.) zero percent financing from the manufacturer, 4.) No questions about how the car was treated, how it was driven, what kind or lack thereof of maintenance the car had, whether or not it had had body work of any sort, had it had hail damage, been in a flood, and so forth.
Face it, the vast majority of car and truck owners do not maintain their vehicles. Not like us car guys do. And the 'Pre-owned' crap the dealers sell (not used cars anymore) and the 'Program cars' you know the ones they bought at auction that had been car rental fleet cars.... forget it. Did you ever know one of those cars that had been treated with respect? I never have
So buying new isn't all that bad. And with today's cars with the electronics and computers and gremlins that can pop up there.............
Bringing this home to Model A Ford perspective, it is the same situation. Do you want a professionally restored Model A Ford that was done right, or some cobbled up farmer-fix rat trap? Best to lay out good money for a good product.
