My former employer had a Bentley, could well have been an Arnarge, bit difficult to remember but....
When he traded it in against a new Continental, we learned the depreciation was effectively £2k a WEEK. No matter to him, it all went on the company books iirc.
Someone caused slight damage to the door, repair cost...£5k
One of the guys used to fill it up for him (he wouldn't generally do it himself)..roughly £100 a week just for commuting, that was back in the early 2000s.
Phew, nice cars but crippling costs for mere mortals.
