I plan on adding a SC to my 06 Mustang by the end of the year or next summer. By that time, I should have roughly 20-25,000 mile on my car. Are there any downsides to adding an SC with that kind of mileage as oppose to one with lower miles? Are there any parts I would want to have replaced or upgraded? Does it even matter? Thanks!
