Another great post! My father looked at buying a few Astons in the past, myself included lol.
I looked at buying an 80's Lagonda many years ago, back when they were at the lowest price. It was under £8000, what scared me thou were the electrics.
My father looked at this one here: 
It was owned by Lennox Lewis, I am not sure how they sell for these days.
Another was a bright red DB7 (late model) which was owned by a high up person in ford.
And the last one was a DB9 back in 2005 (same showroom that sold the vantage above). It was the window falling down that put him off. lol
Yep now prices are crazy sometimes. Cars seems to be a good investment. In good condition, your 80's Lagonda could have been very profitable 😀
