<prompt> Human: hi, say you got a car coming up to 90k, car guys... you know whats coming, all the major stuff - timing belt, water pump, tranny fluid, rear differential etc etc. My wonder is, would it make sense to sell the car at the 90k mark and spend carSoldPrice potentialMaintanenceCost to get a newer, lesser mileage used car? Or should just pay all maintenance and keep car? Assume car has no issues so far. edit: car is all paid off and if i were to buy id definitely pay cash  <response>: Youll just be buying another vehicle that will also have maintenance due at some point.
