Would recommend
Mazda2, 3 and 6 (be mindful the 3 can cost 3k to fix the air con when the compressor dies)
Toyota Corolla, Camry and Cruiser but only up to the 1HZ motor
Nissan Pulsar, and Patrol but not the 2.8 or 3.0 TD
Subaru (Brumby all the way

) Liberty, Forrestor and Outback.
Mercedes, only if you don't care how much it costs to fix it.
Holden Commodore up to VZ
Valiant, especially the E49 Charger

Would not recommend
Holden Astra (god they keep me busy!!!) Zafira, Vectra and Barina
Ford Focus, Falcon (any model from and including BA) Fiesta
Mercedes (if your worried about how much it will cost to fix it) especially anything with a 5cyl
Saab.... any of them
Volvo, as above
Landrover (Sorry Landrover lovers but my guys dive under the benches when one of these comes through the door)
Jeep, coz it stands for just empty every pocket.
