I bought an '89 Civic Si with 160k miles that had been sitting in a driveway for 3 years in 2008 just to fix. It had the typical Civic rust, but everything was there. Flushed the fuel system, replaced the battery, oil & filter, new main relay, plugs, coolant system flush and cleaned the idle air control motor. I fired the car up and it ran perfect. At that point, I had about $500 invested. Since I didn't really need the car, I gave it to my (future) son-in-law to drive. He drove it for a full year and then brought it back. It sat in the driveway for a month, then a friend of my kids (a U.S. Marine reservist)needed a car to drive, so off it went. Now, at 200k miles, the car still runs perfect. The only repair between my original investment and today was cleaning a connector for the cooling fan motor to get the fan working again. Everything works 100%, including the electric sunroof and the a/c. The rust holes have been filled with spray foam insulation and covered with bondo. Red rustoleum is almost a perfect match for the paint and it still gets 36 mpg on the highway and is a blast to drive.
