Yes Finch has a fantastic reputation and from looking at that car it is extremely well done. Considering it is only 2/3rd the price of this Plus 4 on car sales .https://www.carsales.com.au/cars/details/2015-morgan-plus-4-manual/OAG-AD-21762572/?Cr=1 it was a great price, I agree it is surprising it did not get higher.

Looking at a few cars in that auction the prices seemed lower than I expected, quite a nice MGTF for $26,000 as an example. A HQ 2 Door Monaro that unfortunately has a fair bit of visible rust didn't even get a bid, a couple of years ago they were selling for stupid money even if they were rusty.
