I agree with the sentiment flowing that the price is kind of ridiculous- almost in line with zany, over-ambitious Oz pricing! However, it is a mega rare example in what appears to be in lovely condition - and in a fantastic colour.
There were only a handful of Kiwi-new E34 M5’s in the first place. Sadly one was written off, and a number of (including UK and South African) examples have inter- planetary mileage these days.
I personally think this is a $30-$40k car. I know that falls into nice E39 M5 territory (certainly a few more options if you want to buy one of those). However these cars were so rare in the first place - with their engines even hand built! I think this deserves to sit in a nice collection. The values for these (mint examples) are slowly on the rise everywhere around the world.
