Well my search for a newgen engine didn't produce anything for a sensible price, but I did find this.
2011, one middle aged lady owner from new, 4600 miles and only 35 miles down the road from me.
I could not let that get away.
And now I will have to change my user name.
Thanks for all the advice offered, even if it did turn out not to be needed.
