“Among the luxury accouterments available on what is surely the world’s most expensive ute is a dashboard clock — the Breitling for Bentley Mulliner Tourbillon — priced at a cool 150,000 euros (about $160,000). This is on top of the Bentayga’s $229,100 starting price — not that you’d be so basic as to bolt it to the base model.”
Rather than a normal clock, you can get an automatic clock with a tourbillon, attached to a winder powered by the car. I was so ashamed after seeing this that I drove my new S Class into the lake.
