VW Golf 77TDI ... from $27,490 plus on-road/dealer costs. 1.6-litre, 4-cyl turbo-diesel; 77kW/250Nm; 5-sp man or 7-sp auto; 4.9L/100km (m), 5.1L (a); 129g/km CO2 (m), 133g (a); FWD.
Value Lacks many of the goodies but still gets single-CD audio with MP3 and aux input, 15-inch steel wheels.

Inside Well screwed together with a quality feel, if a little austere in base model trim.


Engine Pulls strongly from a standing start but quick to run out of puff. Little discernible lag in manual form. Frugal.


How it drives Crisp steering feel. Solid, confidence-inspiring stance. Optional dual-clutch auto can be indecisive, manual is the best choice.

Safety 7 airbags, stability control, 5-star crash rating.


Verdict Boasts quality fit and finish and an enjoyable drive but it's light-on for standard gear.


Mazda3 Diesel ... from $29,715 plus on-road/dealer costs. 2.2-litre, 4-cyl turbo-diesel; 110kW/360Nm; 6-sp manual; 5.7L/100km; 150g/km CO2; FWD.

Value Satellite navigation, six-CD audio with MP3 and aux input, cruise control, Bluetooth, 16-inch alloy wheels.


Inside Plusher pews and a roomier back seat. Busier ambience — steering wheel has 18 buttons or switches on it.


Engine Punchier, more flexible power delivery produces surprising acceleration. Thirstier and a little more noisy.

How it drives Firmer, more fidgety ride. Sits flat and stable through corners. No automatic option.

Safety 6 airbags, stability control, 5-star crash rating.

Verdict Costs more but its strong engine and solid value re-set the bar for diesel cars less than $30,000
