I drive my 2004 Toyota HiLux dual-cab ute about 40,000km-plus a year. As a 50-year-old, I want a more comfortable vehicle that's able to do some light work. I don't need 4WD. Based on your recommendations, and the look of it, I've had my heart set on upgrading to a Ford Ranger for the past six months. My problem is comparing the 4x2 dual cab MY15 Holden Colorado LTZ against the current Ranger XLT. I've test driven the LTZ and the Ranger and the drive-away deals from Holden are about $8500 less than from Ford. The LTZ has better entertainment, rear camera, better economy, upgraded interior and lower cabin noise than the MY14, and same power and safety as the Ranger.
The Holden is cheaper because more people are choosing the Ford. If it's close enough on features, and ahead on value, then park the dream for some reality. But perhaps also cross-shop the Mazda BT-50, which is a clone of the Ranger.
