i got a 6.2 sec 0-60 (g-tech recorded) with revo, forge dv, milltek dpipe/cat/zorst.. dunno how accurate those things are.
by 80k the cambelt should have been done, check the service history to see if the waterpump was changed at the same time.. they can give up around 80k. see if there's any history of the aircon being serviced (i've just had to buy a new aircon compressor.. not cheap!)
