believe me that car in its first month or two of ownership heard its fair share of swear words from me when i was trying to get it all sorted and running properly!
since then though it has rewarded with decent power, not being toooo thirsty and putting smiles on the faces of anyone interested in cars that it drives past and particularly passengers in it
i'm sure you'll get quite a while out of it before you have any issues, its been my daily, literally driven every single day through sydney since i bought it and never let me down so i trust it will do the same for you (no promises with the race track though!!)
i've come from subaru's so by habit been quite gentle on the gearbox i think its lost traction in the dry in its whole life.. (i had to, it was in front of my ex-work mates at an autobarn store, if you don't leave with a little smoke they'll banish you!)
enjoy it mate! feel free to contact if you get stuck with anything, the UK micra guys know their stuff with these and snikty from QLD is on both forums and has done his fair share of work on his one
