I used Imports101 to import my 180 from them late 2005. Danny is extremely knowledgeable and will answer even the most basic questions you ask him without making you feel like a dick head. If you want to ask more questions about imports101 feel free to PM me or go to imports101.com.au and ask away on their forums.

If you do decided to go down the import path I can not reccomend Imports101 highly enough mate you should have a squiz at the forums and see the R32 GTR they are building, that alone should be enough for you to do business with them.
