Cheap park and fly at the Detroit Metro Airport? -

I will be flying out of Detroit on the 22nd and will be leaving my car from the 22nd to the 27th. I need to find the cheapest overnight parking lot close to the airport. I have found Qwik Park and they offer a 24 hour stay free, but they cost $10 a day. Does anyone know of a cheaper park and fly place with free shuttle to the airport?

That s probably as good as you ll get, unless you have friends who live in Romulus who will let you drop the car at their crib and haul you to Metro.
