Bought 6-28-08, has 19100 on it, didnt drive for a month because of body work, and 11 weeks of driving only 50 miles per week. Had a 04 3s hatch with 54124 in only 20 months ..
ticked off 25k on my 08.5 a few days back, no further problems since the initial radio glitch and the cooling hose falling down into the fan blades....
Now at 17,500. I put a heap of miles on there in the first 6 months to get used to driving a standard. Now I do everything in my power to avoid driving and adding more miles haha
