Hi Foxtbh,
Generally we will always try our best to provide you with a vehicle within the group you booked. If the booked vehicle is not available we may offer alternative vehicles, usually above but occasionally below the group reserved and in some cases we may even include an option to upsell to an even higher group if this is more suitable for you.
Please can you send me your reservation number in a private message and I will be happy to check in with the branch on your behalf. I'll do what I can to help you receive your preferred vehicle.
Best regards,
Gary
