Philippe And others who may planning on going some place besides the gas station. There is an old saying, "Preventive Maintenance Is Cheaper Than Corrective Maintenace". If you have had a regular maintenance program with your car(s) then you should have no need to carry a trunk full of extra car parts for a regular trip. (If you are going to enter in the Group B circuit....that's another story) If you feel the starter motor is going south on ya...change it now and leave your vacation time for you to enjoy. Take your car for a "test" by filling up the tank and driving it non stop to the quarter or (half way) mark on your fuel gage and then returning home. By the time you get home you will know if you can make it. I don't know just where you live at. Maybe you will need to carry your passport for a border crossing. A good tip for all to follow is to keep the engine compartment as clean as you keep the body. If you do this then you can see if you are going from a seeping gasket to a leaking gasket. So the next time you go to a car wash stop by and power wash the engine bay. Just keep in mind that if you drown the electrical stuff you will be there longer than you want. Rodger & Gabby
