My Kamiq arrives tomorrow in Sheerness after 29 days since was build, how long is going to take till handover?

Depends on other cars going to dealership, they are going to try and fill a transporter, and if few thousand cars arrive together on a ship, will need to wait for transporter, so could be anything from 1 day to 2 weeks

 

When it gets to dealership it will need a PDI (pre delivery inspection).  If your salesperson is on the ball will have booked workshop space. But as others needing warranty work or servicing have found out some dealerships have 6 week waits for workshop slots.

 

So handover could be anything from 2 days after arrival, to many weeks before it is ready.
