I have a 9 year old ST24 its done 95000 miles, the last 35000 it has been my tow car. In that time I have changed the oil 5ish times, one set of spark plugs, one front wishbone and one rear wheel bearing. It still is on its origonal exhaust and clutch. You could say its been 100% reliable and cost nothing to run (not including fuel).
