Reputable 4WD mechanics in Darwin?

Hi All, Just wondering if any top end members can recommend a good 4WD mechanic in Darwin.

I drove from Nhulunbuy to Darwin and and back again, and then once more to Darwin for good measure (about 3500km with 2500 of it unsealed), towing a fully loaded trailer (I destroyed 4 trailer tyres and 3 rims on my final trip, but that's another story!)

I've had it in for a grease and oil change (and a clutch master cylinder, but that's another story again), and the mechanic told me parts were hard to get for these grey imports out of Japan. Last I checked, Nissan imported the Terrano II's from Spain, and there was nothing grey about it. Parts are hard to get because Nissan Australia dropped it like a hot potato after 3 years of poor sales.

The old girl's starting smoking a bit under acceleration, and while I was told the brakes and suspension are fine, I feel that I need a second opinion.

Any suggestions?

Thanks, Scott
