If you do the work yourself budget $1500 a year. This includes regular maintenance assume @12000 miles a year driving. If you expect to get someone else to do the work budget $2400. This is a bit conservative but over the time period say 5 years it is really is pretty close to what you will spend yearly. Think of it as a $125/$200 monthly car payment. Save it up and at the end of the year roll it into the next year. At least you get to keep it if it does not get spent.
