I have 3 cars vz clubby which is cammed and stalled, r33 gtr modified and my fun daily Alfa 33 ti. My view is the gtr should not even be placed in the same sentence as a falcommodore. And as for a 35 I could only imagine the pleasure in driving that. I often go on mountain drives and have taken all 3. HSV is by far the worse. Stupid and dangerous chasis, brakes are no better probably because of the chasis, boring to drive because it's just turn in wait for the oversteer and power out. These are just ego cars not driver's cars. Gtr I am not even going to do describe and can't even imaging how good the 35s are if you have the skill. The Alfa 33 is an amazing little car and I can throw that around the twisties like go cart. The Italians really designed this car for driving pleasure. Amazing 1.5L twin Carb motor screams and the chasis is so balanced and progressive. Fwd doesn't under steer like the Japanese cars and you can have a ball with just 95 kws.
So in conclusion. Alfa to put a smile on your face and stay legal while still teaching you how to handle a car (sorry it just keeps dragging me in), gtr for it awesomeness enough said, falcommodore for.....for..... nothing really unless you want a v8 to say you have owned one or skid and drifting but Gen and ls engines don't like hitting the limiter too often.
