the larger vents is a simple easy swap
that shouldnt affect your decision on buying a car at all
wierd...
why cant you make the other one you bought run ? it cant be that major or very costly to fix, then you could sell/trade it for an earlier one if its not already and early one, chevy engines are simple to work on, a monkey can do it and the parts are dirt common
a little elbow grease will save you $ and get you ahead, by far, i dont see what has stopped you from fixing it and either driving it or trading/selling it, i dont understand ? it doesnt take a rocket scientist to work on these old things, they are really super basic., and its highly unlikely you will find a 2500$ car that doesnt need something or other done to it, either mechanically or physically, so..
2500 is really super cheap for a perfect car, in which it sounds like you want for this cheap
look at this ttop one for 2500 its not evne together:
see what i mean ?
