I understand why you're upset. However, playing devil's advocate, what difference does it really make if there are 125 extra km's on the car?
Sure, people may have taken it for a test drive and driven it harder than a little old lady but I can't imagine that any lasting damage has been done. Are Hyundai's really that fragile? As long as the dealer agrees that the added mileage is added to the warranty there shouldn't be any issue.
It's not the number, it's the principle. If the contract says "X", then both parties are bound by "X". In this case, the only party in question is the dealer. He has to deliver a new vehicle with fewer than a certain number of kilometers on the odometer. Even if we put aside the fact that a contract should be a contract, it's a sign of trust and honesty that should be maintained.
I don't claim to know exactly how much leeway a dealer has in these circumstances so let us assume that, in the case of a highly popular car, a dealer does have the right to waive very low odometer readings. In other words, I'm envisioning a situation in which pretty much all versions become demos. These in turn become sold cars as there is none available other than those same demos. In such cases, wouldn't it be better for all concerned to state that up front, thereby avoiding the whole issue? Perhaps a drop in price can be offered, corresponding to the extra usage.
Other than that one situation, I would be tempted to walk away. If the usage is not as expected or agreed to in the contract, what else is not as promised?
On a related note:
- At which point does a new car become a demo?
- At which point does a demo become a used car?
