6/7 seater people carrier

[fidgetmidget]

Looking for a 6/7 seater people carrier for a week if anyone has one and wants to swap cars for the week. Must be reliable and roadworthy. I have a Mitsubishi Montero 4 x 4, insured any driver over 30, but there is not enough room for the 2 grandchildren and parents when they visit.  I have been quoted no less than 300 euros for the week to hire and as much as 438 euros, so someone out there is having a larff!!!

I know its a weird request but one doesn't ask, then one doesn't get...right?
Please pm if you can possibly help.
TIA
