Welcome to Al ’ s Garage . What seems to be the problem ?   No problem at all ! I am taking a long road trip and I want to make sure my car is in good mechanical condition .   Very wise decision . When was the last time you had a tune up ?   Not that long ago , I think it was four months ago .   We usually recommend that you bring your car in every five thousand kilometers .   Why ? I mean , what exactly do you do to a car that you need to check it so often ?
