I often book hire cars for our lease car drivers whilst their vehicle is in for mechanical repairs. You have some excutive car drivers that are happy to use a Focus or Golf while the A8 or XJ is in for repair for a couple days. Then you have those that demand the hire is like for like. My lease car has sat nav, dual clutch, birds view camera and heated seats/steering wheel - I need a rental with the same spec!!!
Yes ideally same spec would be nice however in the short term it's not going to kill you #behumble
