I feel a bit responsible but well done, congratulations and I hope it works out well for you.
I have bought 2 Frasers from the lower North Island but collected both of them myself. One I flew up and drove back, the other I drove up and trailered back, albeit it did come with a trailer, so I have never had to use a transporting company. Maybe buy a trailer as well and do the same. Will cost more but you end up with a trailer which will be useful for getting to the racetrack once you have the car finished. For example http://www.trademe.co.nz/motors/trailers/single-axle/auction-1301877659.htm
I am only partly being smart, depending on how you value your time versus money it might be worth it. In the case that I trailered the car home I ended up with a heap more 'stuff' than I may have if I had it transported, just because I was in his shed and asking questions.
