you change the oil every 10k, i have put 45k on mine since last january, and all i have done is change the oil and one airfilter, the car has more than payed for itself i drive 60 miles one way to work, thats 120 round trip, 600 a week if i only drive to and from work, the car payed for itself and insurance is cheap as hell, it actually saved me more money for my weekend toys, my R1 only gets 50 mpg and thats if i baby it, plus cant drive it daily, my penis does just fine in it too, lol. I'm probably the only guy to have ever gotten road head in an insight lol.
