Saldous,

Speak to HR and ask them to change their policy or make an exception. It is known for some HR staff to be quite reasonable. Our company policy is also for 4 seats, and most guys opt for a Boxster or TT to conform. Try getting 3 clients into one of those.

How many times will you need the extra seats. Simply put it to them to give you the money and let them know that you would have a 4 seater when required (most hire firms will deliver in less than an hour). In addition, if you only have one client, I bet they would love a spin in the XF.

Is there a time limit for you to get 4 seats in the policy. You can say you are trying.......
