Just a word of warning about fast delivery of cars, make sure they are up to date models as I got caught out on my current car being told it had an electronic handbrake and when it turned up it didn’t.
The reason was it was a car that had been parked in a field somewhere for 7 months that dealers were unable to shift because private buyers wanted the cars with the latest stuff in it and then a Motability customer turns up and car sales person gets a big bonus for shifting a 7 month old car, be it a newly registered 7 month old car.
If your happy with the car it doesn’t matter but just saying to check everything you think should be in the car actually is in the car before signing.
