Sorry Dicky, didn't mean to appear to be questioning your sale price, but only that I am genuinely surprised, as I didn't realise this is where they're at value-wise.
As you mention above, it's difficult to set a price on cars like this, as they only come up rarely, sorta like valuing art.
It's certainly one of, if not my favourite of the pre-3200 Masers, and your example looks in fine fettle. I really will be interested to see how it pans out, as it'll give a steer on where the values are heading.
Hope it sells well and quickly.
