my experience is SA won't buy insurance the day they handover the car to customer
usually 1 day before at least

but i do have to say please don't crash the car so fast
because i do have heard from an ex-customer of my SA back then....he literally crash the car within 1st week..unlucky
that customer got banned from buying insurance for the rest of his cars after that

well, nobody expect to crash their car within such a short period of time

actually nobody wishes to crash their own car at all

but business is still business
depends on case by case i guess

happened often enough, insurance will ban u from renewing it
u of course can keep buying new cars...keep switching different insurance company
policy will become tougher and tougher...want this and that from insurance company

from what i heard, that's not his first time already
