    The Roving Wheels:

    (circa 1970)

    These days you need a car that'll give you a run for your money, a car that keeps its new car feeling, that makes you glad to get behind the wheel and drive. Dollar for dollar Holden gives you so much more. Its a special feeling when you own a car that stands apart wherever it goes.

    A sense of style, security, success. Our Holden Premier gives us all that in the most satisfying and luxurious way. You ask me what I think of my Monaro? Well its hard to explain - it must be the sporty feel, its more alive. Its not just the way it looks, the way it drives, everything. Monaro - its a way of life, and I like it...
