For me it was the Dashboard.
As an eleven year old I was obsessed with cars, particularly the dashboard for some reason! I used to walk past parked cars, peering inside, must have looked odd! The ones I distinctly remember as my favourites were Saab's ( as they looked like cockpits) and of course 75s all the walnut and those retro speed dials.
When I passed my test, I bought a sensible first car : a Yaris, kept it 6 months then bought a silver 75 Classic.
Probably the most basic 75 you can get, but most importantly I had the Dash!
On number 3 now, my lovely Dorchester!
