Some 15 years ago I tried buying some new parts from Ford for my Sierra Cosworth 4x4.
Ford told me: Sorry but the car is older than 10 years. We don't sell any parts anymore.
I then said, O.K., I'll use the parts from the Escort Cosworth, that's not 10 years old.
And Ford said: We know, but these parts are out of stock and we are not going to order a new batch.
So, don't expect to find many new parts.
