I hate been vindictive but just be VERY careful as when you signup to a service of a broker as you are only sign away a fair bit of the ground you may be able to stand on if something goes wrong.
My best bet if you don’t want to do the hard work, is, J-spec. At least they avoid the notorious dealer/s that other major mainstream brokers use, which is a damn good sign. Plus I have read here from poeples experiences that they will rectify any issues that you may have once your car gets here.
I take it that you are in Perth given your interest in import101?
If so go check things out locally. Paul at Autoworx is a genuine guy who looks after his customers, and has some killer bargains. Autoworx is good, as he is legally a car dealer as well as offering a broker service.
Another one is if you want top quality you can not go past Auto Wholesalers on Shepperton Road Burswood. They are great, I take all those I help import there, as I know I wont have any issues with them complaining to me if there car has an issue, and you get a 3 year warrantee standard. Just that says a lot about the faith they have in there cars.
If there is a slight chance that you want to import yourself, I HIGHLY recommend that you do a search on my user profile to receive all post posted by me. You will find a lot of information, and feedback with what other people have said. Information here is as good as gold.
At the end of the day it is an option which you have to take up yourself. It is very good you have taken the actions in getting information from those that have imported.
I'll end this post with rephrasing that,
The Best advise is to you is to READ what you are signing away, (your own ground that you stand on) when you signup to a service.
