I think a lot of people are getting emotional about a home grown car. I will stand by what I said, the Commodore is not a fast car. 12 second quarter? Still slow. Compared to smaller, lighter, performance based cars. But it's all relative. The Commodore was never meant to be a sports car. It holds it's own with large cars the world over, but my point is, it's not a "quick" car.
Throw enough money at anything and it will be quick. I've had a Busa, I've ridden an R1, a CBR1000RR and a GSXR1000, they are quick. I've done track work with ZX14, that was scary, too big a bike to throw around a small track where a 600 holds the lap record. During my life I've been exposed to all sorts of cars having worked in the auto industry on just about every level, Euro cars are quick. Jap cars are quick. The W375 isn't really a Commodore anymore, not what is sold by a Dealer anyway, it gets choofed off to a performance shop for modifications.
I'm not saying that other cars are necessarily better, just quicker. The OP says he is disappointed a bit with the end result of a W375, compared to what? That's what I was doing, comparing it to quick cars. As it is, it's not exactly a slug, but when comparing to a car that is actually built for speed and acceleration, and I mean a production car, not something that has had an additional $6K thrown at it, then the Commodore is not a performance car. I think we, as Australians, are too far away from real performance cars. There are a few on the roads, and our legislation makes them out of reach for the average Aussie. Come 2018, I think we will start to see some real cars on the roads.
