Used to do most all my own maintenance. Once one gets older and has enough to pay others to do it, one starts keeping them less time. At one time, we had a 1983 240D Benz and a 1996 Tacoma and a 1997 VW Cabrio. Now, we're newer with a (monstrous) 2005 Tacoma and 2010 VW Jetta and a new JD 1025 and don't plan to keep them past 6 or 7 years (will on the Tacoma unless SOMEONE finally gives us a nice, small pickup again, ideally with a turbo diesel engine).
