I'm yet to locate a good US supplier for importing the consumables and various parts for the GC. I have posted somewhere before, but I import all my filters and spares for our SRi-V Holden Cruze. According to the wife that is my car when the Jeep arrives..
On the Holden I imported $950 worth of Holden priced products for $480 delivered to the front door including freight. All OEM /same part number from GMparts online. We are easy targets when it comes to the cost of parts and they know Aussies will pay it..
Spent most of Nov-March living in the US and the price of the SS Commodore in the US (Chevrolet SS) is about 10K cheaper there after it has been freighted from Adelaide and is kitted out with more features than what we get here. Not that that has anything to do with importing, just frustrated the hell out of me while I was there... Why are we paying more in Aus.
Long winded, but when the Jeep arrives I will locate a good US parts supplier and try and save a little on the consumable items over the long term.
Will keep you posted if I locate one and will watch your thread with interest to see how you go.
