Have something of a business trip tomorrow, and no longer trust my Jetta. My truck would burn 30 gallons of gas for this trip (600miles I estimate); wife needs her Camry and while I will drive farther I don't think she wants to drive the truck (she did not offer that option while she argued with me to not take the Jetta). So I tried looking at Hertz and their quote was $141. Looks like Enterprise is similar. I need to pick up at 6am and return at 9pm, that won't work, so 2 days of rental. Close to $70/day. So fine. Talked myself out of a rental. [Truck would cost $96 in gas, a 30mpg rental would be $64, spend $140 to save thirty bucks and wear/tear on my truck? does not compute.] My question: do they get much cheaper if you rent for a week plus? Sometimes the thought is that one can rent a car if they think their jalopy won't make a trip, or if said jalopy down for a few days for a repair. Seems like a week at $70/day would make two car payments! That sort of money would indeed pay reg&ins on a jalopy that is kept strictly for this purpose (main driver down).
