Mileage mainly... I commute to work every day and prefer the higher mileage of the 4cyl model over the 6. Cost is the other factor, I got such a great deal on this one, the dealer said that to get a v6 model outfitted the same would have been about $2500-$3000 more. This one was near the top of my budget.
Besides, since I don't race or anything, the I4 has plenty of get up and go for me. Hauled butt on my test drive, since the salesman at the dealer decided not to go with me!!! :fawk: them!
