I agree with DJW38uk.
To just rush and get a car that’s available in a week can mean you find out that ut does nit suit your heeds when you have the car in your drive and can be saddled with ut for three years.
First thing you need to do us work out,
how big you want it to be
Boot or hatchback
What specific items do you need (I.e. heated sears, electric seats, dark/light interior tinted rear windows etc, etc)
Once you have done that you MUST test drive, so many regret not test driving before signing the contract.
Then,mwhrn you have a list if xars, check with individual dealers if they have cars, in, for example,navy colour available, or what lead time will it be.
I’m afraid you may find lead times are 12 weeks or more,bas suppliers have a just in time system today.
Don’t forget, until you get the car, your motability aspect if pip will be paid into your bank account, so you can yse this for taxis etc
