You've got me beat, but it's suprising what's hiding away in neighbourhoods.
I live on a 12 house Cul-de-sac and we have:
A '65 Corvette roadster, a Volvo 1800 ES, a brand-new 911, and Triumph Trident 750 (motorcycle).....all at different homes.
The Volvo guy also has an original Toronado.
Plus all my stuff.
The former owner of my house also had a Volvo 1800 ES and before that, a TR4.
