I have a 2001 PT with the factory Chrome Plated Rims. I lost the center piece.\nIt's a plastic disk about as big as an old silver dollar. .10 from a dealer.\nWow!!!!\nAny idea where I can get a better price on this item.\nAlso, in about 500 miles, I "need" to have the spark plugs replaced and the\npower steering fluid changed. The dealer wants 5 labor to change the plugs\nand to change the power steering fluid. This seems pricey. And why does the\npower steering fluid need to be changed?\nAnd no, I won't consider changing the plugs myself. They also said I could\nbring my own plugs. Any brand reccomended for better mpg?
