Well, it's a large car. They usually cost losts.
I found the current
Holden Omega is totally different from the last
Opel Omega, while the old Holden Omaga is basically identical to the first Opel Omega. Omega's have been discontinued by Opel in 2003. I don't know why, as they sold good. Maybe they wanted to get rid of cars with rear-wheel drive.
