Sounds like the dealer was throwing you a curve ball hoping you'd strike out and he'd walk away with your hard earned money. The dealer I bought my 95 Sonoma has tried to get away with this type of BS. Needles to say I won't be buying from him anymore. It's amazing how greed can ruin a once good relationship. And the sad part about it this dealer knows that I would not fall for this BS but like I said "Greed can trump common sense"!
