FYI, be aware of a "disappearing deductible".
This is a $50 deductible that is waved by the location purchased the ESP, but any other dealership will charge you $50 everytime you bring your car in.
If you are a decent mechanic with a garage and tools, I'd skip the ESP.
I did not opt for an ESP on my current Focus because I knew I'd play around with it.
