<prompt> Human: I have a 2010 Nissan Rogue which has been pretty problem free, 110k miles. It does this random clicking thing when going onto highway on ramps, but it maybe happens 1x per month, havent gotten it checked out I just go slow and turn the radio up! Im thinking the maintenance is going to start creeping up soon.I work for an energy company, and they have a deal through Nissan where we can get a Nissan Leaf with 10k Nissan Rebate, 7.5k State Rebate. The top line leaf starts at 37k so figure trade in of 5k for my trade in and 5k down saved after I paid off the Rogue. 0.0 financing for 60 months on 10k is a 166 dollar payment. I live near work where I can charge for free and typically pay around 90mo per gas. So considering that its like getting a NEW 37k Nissan leaf for 80 bucks a month.Am I missing something or is this totally a deal and I should jump on it?!  <response>: Do you have a second car for longer trips? If so, go for it. However, 110k on a rogue isnt about to creep up. Youll have the 120k service and 170k service, but otherwise the rogues arent bad on maintenance. However, if its an awd youll have more parts, more weight, and more fuel. Flipside is lower registration and insurance on older vehicles. Figure out the registration, insurance, fuel cost differences and an estimated maintenance cost. Put all of these in, its some big math to do a cost benefit. And include the human factor. The reason I have my Mazda instead of my old Jeep is because the human factor said nope get the Mazda even though dollars and cents math said keep the Jeep.
