I doubt they will disclosure numbers for the Serie 5.
I do wonder... they seem to be making around 1 1/2 Aeros a week.
I'm basing that on the time it took to get from my chassis #80 to chassis #100 to the same stage of production.
& extrapolating that to the last build slot being Sept this year (I hear), then that's around 140-150 cars, give or take factory shutdowns.
I'm sure further digging would reveal a more accurate count. Or simply watching the chassis numbers as they go through the factory (assuming they're produced in numerical sequence!)
