Back in the 1980’s Crewe needed to sell (from memory) around 75 cars a week to break even, and it was often quite close. Cost control measures apply even at the top end of the market.
Another little anecdote from that period:
Top speed of the then current turbo cars was limited to (again, from memory) 135mph by opening the turbo wastegate to dump boost. When my mate asked why I thought they did that my guess was that it was done to limit temperature load on the tyres, but I was wrong. The issue was that at high speeds a low pressure zone existed around the top of the doors, and the window frames weren’t stiff enough to resist the resulting force, meaning that they started to pull away from the seals giving rise to increased wind noise. Limiting the maximum speed to a number that kept the wind noise low was a much cheaper solution than re-engineering stiffer window frames.
Over a few beers, I did suggest to my mate that they could offer a chargeable “high speed kit” to customers, that would include removal of the speed limiter. The wind noise would be cured by putting an eye bolt in the top of each window frame, and then a length of piano wire with a turnbuckle in the middle would be strung between the eye bolts, across the car, and tightened until the wind noise was eliminated. For some reason that escapes me, he didn’t think it viable
