What is the best route to go down when arranging collection of a new car?
Just ask them to peel the stickers of and hose it down ?
I went one step lower than that.

Dealer was asked to only:
- Peel off stickers (so they can PDI it), but leave glue residue on (imagine them scrubbing away with industrial solvent to get the glue off.
)
That was it. No hosing down.
I collected the car - it was dirty, covered in glue residue (mainly along roofline and sills), windscreen has marker pen writing on it, and sticker marks. But the paintwork was totally swirl and scratch free. I drove it home and sorted it out myself.
Obviously if you want the whole 'unveiling' experience the above approach is not going to work, but if you value your paintwork it's worth forgoing the ceremony IMO.
