i'v had my 2002 corolla for 3 1/2 years,, got it on 44,000km and now coming onto 200,000km, and done at least 4 track days in it. cars been mod'd and then returned to almost stock (suspension and brakes only) was serviced every 5,000km up untill about 12 months ago (when i stoped tracking it) now service every 10,000km. the last 156,000km has only tasted premium petrol, last week i averaged 7lt per 100km.. they say 1 lap is equivalent to 1000km wear and tear, last track day i did 26 laps around winton. fuel and services has cost me a small fortune (at one stage i was servicing every 5-6 weeks) but i would not change it for anything.. great car..
