My only point is that there's not enough more probability of a problem with a V6 to even worry about. I've owned a number of both types, and there's just no difference in reliability of inline vs. v-type in my experience.

I've got a 2- part answer on that one:
A) that's one reason I picked the Intrepid- north-south engine layout, simple access to everything, no plugs or manifold tucked up by the firewall at all. LH cars have to be some of the easiest-to-service cars made since the 70s. But truthfully, by the mid 90s even the transverse V6s had gotten pretty easy to deal with. You might have to remove an intake plenum to get at the rear plugs, but they made it relatively simple to do that.
B) Wanna look under the hood of my wife's PT??? There's an inline 4 that has to have its plenum pulled to get at the spark plugs.

As long as its an inline 4, it will have a big 2nd-order imbalance... nature of the beast, inline 4s are inherently buzzy. Balance shafts keep the whole assembly from vibrating as much, but they don't reduce the internal stresses on the bearing saddles/caps, crank, main bearing bolts, and other internal parts. The crank shoves up on the bearing saddles and the balance shafts pull down on the block (then vice-versa) to smooth out the feel for the passengers, but they actually can add stress to the engine itself.

I agree, but I think there are far more factors that matter more than whether the engine is a V-type or not.
