yea, but with the I4, you do not get the HomeLink system, gorgeous 17 inch rims, hydraulic-lift hood, and finished trunk lid just to name a few.the advantages of these additional goodies for me make up enough for the price difference to get that awesome v6. well maintenance to me is negligible from car to car. unexpected things do go wrong with vehicles involving costly repairs in the long run. with my v6, it will pull 30-35 mpg all day on the highway and still be able to get 26-28 mpg in mixed driving. i assume about 22-23 mpg with 100% city depending on driving style. im not a real light-foot with my car either, but i dont speed unnecessarily on the highways or local roads.
