Welcome to the Forum Ken, or at least the more public "actually posting" side of it
Your question is more complicated than it seems... It's very much different strokes for different folks
To relate my own personal journey, I started off with a couple of restorer's dreams (complete but full resto jobs) and played around with them for a couple of years before realising that it was going to take way too much time and self discipline to get even one of them on the road.
With funds being low, I then bought the cheapest registered Moke I could find (about $5K) and have spent the intervening years gradually fixing it up and improving it with a mixture of essential repairs and long dreamed of improvements. This is NOT the easy way to do it, and probably not the best way, but the definite advantage is that despite a low budget, I have had a usable, registered Moke for (most of) the past 7 years while I'm doing it up. In my particular case, the alternative probably would have been either a half restored Moke still in the shed, or a couple of thousand in a Moke account in the bank for the Moke I'll get "one day"
So that's worked for me, but an easier way if funds allow, would be to buy a better Moke for at least $10K that's likely to be quite serviceable and hopefully allow you to focus more on improvements that you want to do, rather than those that you have to do to keep it roadworthy.
The easiest way of all of course, is to spend $15 - $20 and just get a good restored Moke that you can simply drive and enjoy
. If you go down this route though (or any of the others for that matter), try to find someone who can advise you and make sure you get what you are paying for. You're in Melbourne, so maybe a good idea to join the MOA and draw on the wealth of knowledge there.
The other end of the scale of course is to buy a fixer upper, strip it back and start from scratch. The advantage here is that you can build it your way and you get the satisfaction of doing it yourself. The disadvantage is the huge amount of time and money involved in getting there, and keeping the enthusiasm up while you get there.
Unless you're a really experienced car restorer, you will probably find that it ends up costing way more and taking way longer than you anticipate
. For those dedicated few who can do it though, it can be very rewarding. I would say though that if it's your first Moke, you would be far better off buying a complete vehicle rather than a body with boxes of parts included. For a start, they will tell you it's all there, but it's probably not... Also, it's much easier to put something together that you pulled apart yourself.
Which ever path you choose, keep posting your progress on here. It's a two way street - we'd love to hear from you and you will be sure to get some useful feedback.
