Nothing yet, slight exhaust resonance can be heard however I hear this is something to do with the heat transfer plate under the car, and that it is inherent with Pulsars.
I love this car, After having the Corolla for over 4 years (which didn't have a/c or power steering) this is like a dream to drive.
It has great pickup, I could do 100km/hr in 2nd gear with it still having space to go before redlining.
It handles extremely well, and the power steering provides enough responsiveness while maintaining the light response.
I find the a/c can take a little longer than my mum's Excel to cool the car down although this may have something to do with the fact that my car is metallic black :) and that it is a bigger car.
The car is comfortable to drive. There doesn't appear to be much leg space in the back seat as both my girlfriend and I like to have our seats back a bit, but it isn't too bad.
Braking performance is good and the pedals are very responsive.
Living in Australia and being from the country the car is required to travel at high speeds for long distances. While I haven't done that much driving in it yet, it does appear to sit very comfortably at 120km/hr or the speed limit.
My model has the spoiler and alloy wheels. Along with tinted windows and the colour the car looks very sleek and sporty.
I own one of these babies as well however a 98 model.
As mentioned, they are great cars and very reliable. One thing, however, which is a little annoying is where the engine is revving to at highway speeds (110k/hr). 110k/hr gets you 3500rpm in 5th! Yes that's not too bad considering the redline is 6900 but the ga16 is a fairly noisy engine and eventually becomes annoying.
