Hi Mark,
yes I have just ordered a Mk4. Generally I found FFR good to deal with but I do have to say if you want to talk with them, do it on the phone. They kinda suck at answering emails. I set-up a skype account and use that to ring them, works out quite well.
As for rego well I am feeling confident. In WA we seem to have a reasonable system here that does allow some common sense so I am hoping that continues. Also, there is already a Mk4 here in Perth, and another on its way, so there will be three of these fronting up for rego. Between us all I am hoping we can get it through.
The car is not supplied RHD, so a small challenge there. However, these cars are pretty symmetric so I do not think this will be too much of an issue. Will just have to play it all by ear, see how we go
