Do it yourself, you'll feel real good after and then you can drive the car to a shop and treat yourself with the money you saved, only 5 things to remember when changing oil, warm the car up first, park it in a flat surface, leave plenty time to put it in as its slow to settle, have plenty trays/buckets and the most important use a ring spanner (NOT an adjustable) to undo the plug coz they can be real stiff...........Steve
