Thanks. I do only highway driving with this car, in fact the last 15000 km's have been really only to work in fishermans bend and back.
Ive just replaced the o2 sensor which saw the fuel economy lift from 380ish to 500km's per full tanks which I think isnt that bad considering the performance these cars have.
The suspension is stock as are the brakes. Ive changed the pads around 100,000 km's along with timing belt, every fluid in the car, and I mean every fluid, plugs, etc. The car drives fantastic tho, much better than having aftermarket suspension, at least for what ive used it for. But ya, everything is in top condition and roadworthy
