An agreed value policy is typically for cars that might be worth more than the simple "year, model, miles" formula. Not sure why you'd need an agreed value policy for a Boxster where the value is easily calculated and market values generally agree with the depreciation formula.

I use insurance to protect my assets and for "worst case" scenarios, not to repair a $10K car. Therefore, I have $3M in liability and very high deductibles (which means that I pay out of pocket for what would be a typical fender bender).

And as San Rensho said, get as much uninsured/underinsured motorist coverage you can get. When my silver Boxster was totaled, the driver only had $15K (the Cali state minimum) in liability insurance and the cost of the power pole that she hit was $12K itself. Thus, she was underinsured and my insurance had to pick up the entire tab to replace my car.
