Australia has a rich history for classic car enthusiasts as historically British cars were imported in large numbers.  The warm dry climate means they don't rust away as they did in their home country.  Many American cars were also imported and Australians have a great affinity with the American classics of the 1950s and 1960s.  In addition to all that, their home produced Holdens are deeply embedded in the Australian psyche.  Examples of all of these are now available for hire; from Chrevolets in Sydney, Cobras in Perth, Holdens in Toowoomba, Mustangs in Leongatha and Tasmania to Pontiacs in Brisbane. If you fancy something more modern then you can choose between a MINI Cooper Cabrio, BMW Z4, Nissan 350Z among others.

The Australian climate is ideal for cruising in classic and modern sports cars.  The Australian summer from Dec-Feb is warm and sunny and you can enjoy lazy days on the beach and typical Aussie meals cooked on the barbecue. Summer is the rainy season in the tropical regions in the north that brings the lush rain forests to life. Spring and autumn are mild and are the best seasons for bush walks and discovering nature.  The Australian winter from Jun-Aug is generally mild, but offers snow on the snow fields in the southern mountain regions. At the same time the northern states have balmy 24 degrees Celsius temperatures.

No matter where you are in Australia or what season it is, if you are driving with the top down, always remember your sunscreen. The Australian sun can be quite strong, so it's best to wear a shirt and put on a hat even while driving. Sunscreen containing SPF30+ coverage is recommended.  If it gets too hot in the sun, then choose a car with air conditioning.
