Welcome to the forums. 45MPG sounds great, as far as I know that's the highest MPG on a Versa. 
Looks like you and I are the most active 1st gen 1.6s so Im glad to hear this. The car is deff. slow but I find it to be very reliable. Its also great on gas, and looks decent so its a keeper. :thumbsup:I'm sure this car will last you 170,000 miles. I think you added a extra 0 to your xterra's mileage. My versa though the older model, has the same engine and it's showing no signs of slowing down and I'm at 85k miles. It drives and feels exactly like it did new off the showroom floor.
The gear shift is not moving forward enough to release the mechanism that controls whether the key can be moved to the off position. I have had to push it up and wiggle it a few times in order for it to release whatever it is that stops the key from turning all the way off.Welcome to the forum when the key get stuck did you try turning the steering wheel I have to do that sometimes to get it out. Great mpgs by the way.
