Return Policies for car or motorbikes purchases in Poland?

I was just wondering what the law states about returning a car or motorbike back to the dealer if you found some problems soon after purchasing it. I know that in some countries as a buyer you have the right to return an item to the supplier if you're not happy with it or if the supplier/garage didn't tell you everything before you purchased it. Is there a law like this in Poland to protect buyers?

It's possible if the vehicle turned out to be contrary with the facts described by the dealer. You need to prove it. It is worthwhile to have expert opinion about the car from authorized service or a certified automotive appraiser. If the car has a faults which were not mentioned in the sale agreement, you can fight off the car dealer for the recovery of your money. You have one month from the time of discovery the defect. Buyer can not cancel the contract if the seller immediately replaces the defective things or remove them. But you can still demand a price reduction of the car due to existed defects.
