Just to set things straight I've road tested all 4 Aussie production cars in GT4.
- All cars were bought brand new for the test ie. 0km on the clock
- All cars were only given a car wash before hitting the track
- All driving aids set to 0 and no changes to factory setup (tyres, camber etc...)
- Reloaded game from 2nd memory card after each car to run the cars under identical B-Spec ability
- Tsukuba and Nurburgring - times are first lap out rolling starts ie. no "hot laps"
- Trial Mountain - times are first 3 laps out after rolling start
- B-Spec left set on 3 (medium pace)

FPV GT 
Tsukuba - 1,12.054
Nurburgring - 8,34.325
Trial Mountain - 1,53.128  1,47.015  1,46.869  average = 1,49.004
Notes:  Probably on the brakes the longest of all cars tested, and plenty of body roll too.  Was able to stretch its legs on Nurb's long final straight.
FPV F6 
Tsukuba - 1,11.689
Nurburgring - 8,36.910
Trial Mountain - 1,52.139  1,46.379  1,45.917  average = 1,48.145
Notes:  Showed plenty of neutral slide around Nurburgring.  Changed direction very quickly around Tsukuba and Trial Mountain.
Holden SS 
Tsukuba - 1,12.805
Nurburgring - 8,47.518
Trial Mountain - 1,54.316  1,48.061  1,47.592  average = 1,50.004
Notes:  Looked good under braking but lacked straight line grunt.  Took the best line around corners.
Holden CV8 
Tsukuba - 1,12.332
Nurburgring - 8,40.512
Trial Mountain - 1,53.378  1,47.267  1,47.207  average = 1,49.284
Notes:  Looked smooth and in control at all times.  B-Spec liked sliding this one to the outside ripple strips on exits.
Pontiac GTO US version of the CV8
Tsukuba - 1,11.609
Nurburgring - 8,41.030
Trial Mountain - 1,54.766  1,48.930  1,48.052  average = 1,50.583
Notes:  Had the least amount of body roll.  Better gearing would see this car improve times easily.
Chevrolet Corvette Z06 (C5) Same base engine as SS and CV8
Tsukuba - 1,09.093
Nurburgring - 8,10.015
Trial Mountain - 1.48.835  1,43.245  1,42.823  average = 1,44.808
Notes:  Being a purpose built sports car, it is no suprise that this car is fastest.
Ford Falcon XR8 V8Supercar '00 
Tsukuba - 58.955
Nurburgring - 7,13.167
Trial Mountain - 1,33.876  1,28.817  1,28.142  average = 1,30.278
Notes:  Glen Seton set a high speed record in this car in '00 - 301 km/h at the end of Conrod Straight - yet it tops out at 271km/h down the 'ring's long straight!?
