I agree with making sure the upper and lower manifold gaskets have been replaced, either that or plan on replacing them yourself at some point. Its usually a matter of when, not if, they fail.

That said, I think Id probably take a 3800. I prefer the powerband of the 3800 for daily driving. The 3800 has a tremendously flatter torque curve and makes nearly the same amount of torque from idle all the way to its peak.

The same cannot be said of the 3.5, somewhere around here theres a dynograph of both engines side by side. Its not that the 3.5 doesnt make good power, just seems to me like you have to drive it a bit more aggressively to get it.

Economy-wise theyre about the same. Reliability wise Id honestly have to say that the 3.5 is more reliable simply because it doesnt have the intake issues the 3.5 does.

I cant say for sure which Id buy, right now Id probably by neither, my next vehicle will most likely be a Jeep, much better suited to me.
