Finally picked up the car. The car has around 100k miles. Before doing any upgrades I want to make sure that all the maintenance is done. Due to limited time to work on the car the 120k service will be done at the shop. I read that injectors will fail in the early models so that's 2nd priority, might as well go with the upgraded injectors but which ones? And where do I go from there? As far as I know the car has no issues as of now. Please share your expertise on what might go next and what can be replaced to prevent any future problems.
