Holden makes a fantastic vehicle, they continue to receive accolades but most over here have never heard of them. They are bringing their newest award winning vehicle here soon, and it has just been rebadged as a Chevy SS. It's a badass V8 machine that's well built. I own the previous version of this car, Pontiac G8 (aka Holden Commodore) and it's a solid, well built vehicle that's a lot of fun to drive. Just check it out as they are being made only after ordered by a dealer.
No matter your decision, best of luck! A car purchase isn't to be taken lightly.
