Really? Where? Do you have the add or do you know the owner?
From the photos it looks very clean, and if it is in the same condition inside and in the engine bay, then it's a good price. Being a pre-'71 model with the smaller bumpers and cleaner trim makes it more valuable as well.
I do spot a small bit of rust on the front valance, but the rockers look clean just by looking at the [albeit crappy] pictures.
It's in a MUCH better condition than that polished turd tii that Hampton's want to rob someone with though.

EDIT: Found it on Gumtree without the a price.

It's a '68 model, so (if it is stock) it should have the older type subframe and diff that makes parts a bit harder to find. Seats were redone, but with incorrect materials. Door panels were also redone, but not stock looking. Dash seems to be crack free. Chrome trim on the dash has been sprayed some aluminium looking finish. Late (>'73) AlpinA steering wheel.
Few discrepancies aside, it is a very good looking car in a VERY rare colour. I like it.
