In the UK, the term classic is used very loosely to describe mass market older cars that we males may have had our first sexual experience in.
Cars like the Ford Escort and Capri never set the world on fire, at least until Uncle Henry decided to rally some of them. To me, the Ford GT 40 is a classic, but the fastest Escort on the planet will never be.
REAL classics need a few things going for them.
Scarcity is one, uniqueness along with this if possible. This implies production numbers world wide need to be low.
They must also be desirable, so a seductive shape is a help.
Usually, though not always, they will be sports cars or coupes.
They need dynamic ability that is an order of magnitude better than mass market offerings.
They need balance in how they look, how they perform, and the interior needs to be either outright sports utilitarian or else upmarket and opulent. Generally, REAL classics will have originated as design studies by some of the great design houses.
I think the SVX already is a classic, but I will not be storing mine away. Rather, I will be storing away in my soul the hours of driving pleasure it gives me, especially when the transmission is working.
