So I insisted at the garage if they could get me a quick release for my spare steering wheel ... and I finally got an official response from MMC …

As we say in Spain "grab that curves come!": If you want a quick release, you must buy it along with the steering column. It is not sold loose but as a "set". And for the stupidity of 1300 €.

Yes it's not a typo: ONE THOUSAND THREE HUNDRED EUROS.

Are they nuts?
