 I drive a company issued 3.9L cargo with maybe 200 pounds of extra weight in the rear. The driving dynamics are odd to say the least.  It tends to stay on center, but it does not like to turn. The ride is smooth, but noisy.  Combined gas mileage is 20 MPG, which is not too much of an improvement coming from a full size Ford E250 with 5.4L V8 that got 14 MPG on average.  On quality, they painted the hood support rod to the hood and paint was damaged.  At least I won't see it that often.
