Okay but here's a scenario,
Last summer I actually broke two of my alloy rims driving through a construction zone in Toronto and all I have is my winter's because I haven't had the time or money to buy new summer rims or repair my cracked 17's
Then what?
Or how many people sell the OEM rims when they get their car to put something nicer on, I don't think you'd be returning your buyback car with a nice set of 3DSM's or BBS's now would you?
It's not an issue to return the car with steelies installed, even if the car came with alloy wheels. It has to have "wheels". (I would not push your luck by returning it on 4 temporary spares, though. That could be interpreted as "stripping" and that's a no-no.)
It's not an issue to return the car with an aftermarket radio. If it came with a radio (and they all did), it has to have a radio. It doesn't have to be the stock one. It doesn't have to be working. It has to have "a radio". It could be the broken AM radio from the junk '74 Buick that your neighbor uses as a field car. But it has to have "a radio". Otherwise it could be interpreted as "stripping" and that's a no-no.
It's not an issue to return the car with dented and scraped fenders and the bumper cover hanging. It came with fenders and bumper covers, it has to go back with fenders and bumper covers. They don't have to be pristine. It has to have "fenders". It has to have "bumper covers".
And so on, and so on. I don't know how else to explain it. It has to be "the complete car". It doesn't have to be "in pristine original condition". It just has to run, and it has to be (essentially) all there so that you can legitimately say that the car is not "stripped".
If you return a car with collision damage, it's highly unlikely that someone is going to make a fuss about MINOR missing parts that could legitimately have gone missing as a result of the collision.
The one that my sister has, which she inherited from my dad (who bought it new), is going back with evidence of ownership by an eightysomething owner ... there was a wee bit of parking by feel towards the end, by the look of it. My dad never had knowledge of VW's shenanigans ... thankfully.
