Hi there, I live in WA and have seen a few of those Brunswick cars, neat. But the other option would be Perfmax. They bring in Lhd nd convert to RHD or source US car made for the RHD market. Had two dealing with them on Highlander Toyota and seem a good outfit.

I have one as well. Moved from a Bountyhunter with target ID etc. Have only just started going out with it, still digging bottletops but just a lot deeper :)
