cars have no feelings. wag kang ma-awa sa kanila.
buy brand new if you can afford it. buying used for practicing, especially a cheap one, may just be inviting more headaches because of defects brought about by age, etc.
it is not easy to learn how to drive, if one has to encounter defects in the vehicle.
besides, once you learn how to drive, re-selling that learning vehicle will be just another potential problem, especially if there is garage space for only one.
my opinion.
