Re: And then billed 3 extra hours?
indeed, and the same is true of base model GM cars (Vauxhall/Opel/Holden)... or was up until the early naughties. Most of the kit for the higher spec was there, but either not connected, or a link removed, but ONLY on SOME cars (it seemed random)
Turns out it was a manufacturing thing, they'd estimate demand for each trim level, and if they had any uncertainty, equip more vehicles at the higher spec, and then disable stuff to downgrade if needed.
I got UNlucky with my Corsa, 2 wire harness to the doors instead of the full 14 wire one, so electric mirrors/windows would've been hard to retrofit :(
