5thgenMax hit it right on the money. You would almost think that's he one of those guys that does all those things he knows it so well.
Anyway, if you are out of town I would suggest you jump out the core as I suggested above, fill it with collant and get it home. Then you at least shop around or go to a place that you trust. As stated above, if they know you are stranded you are done.
Good Luck
