If a DtD customer pays the same overall OTR price delivered from Kent to Scotland as one living in the Home Counties then it’s not unreasonable to hope for a tank of fuel and a keying if collecting from Kent.
Depending on the dealership, a key ring on its own might be a big ask.
My first DTD bought car was a 2005 MK5 Golf GT 2.0TDI 140 PD. I drove down to Lookers Burnley to pick it up (about 120 miles away). I was 5 mins late for my time slot and the tosspot sales guy made me wait a whole hour because of it- he'd started the appointment after mine 15 mins before my arrival anyway and decided to have a tea break before dealing with me.
He fetched my pack for the car (manuals, keys etc) and sighed loudly when he saw my keys. Someone in the dealership had committed the heinous crime of putting a Lookers keyring on each key. He muttered under his voice " they know to only give 1 keyring" and wrenched one off one of the keys right in front of me.
He went away to get the finance docs and while he was gone, I took the keyring off the other key. When he came back in the room, I said he could have that one back too.
I felt like Charlie Bucket handing back his everlasting gobstopper.
