Acceptable production to delivery time period?
 

Hi guys.
Took delivery of my shiny new Sonata 3.3L today.

Looked under the hood, and the aluminium engine was covered with white
corrosion spots. So I'm thinking, how old is this car.

Bearing in mind I took delivery on the 1st Sept, the car was produced 15th
FEB.
BTW, there is a different plating system in the UK to the US, for example.
The plate that shows the VIN is on the engine bulkhead and does not show a
date. As far as I am aware, and from what I can see, there is no production
date anywhere on the car. I got the date by asking the dealer. I would have
checked the date before paying if it was easy like the US system, but
because you have to ask here, I though I would try and make the buying
experience as painless as possible and not ask, that is, trust Hyundai to
treat their customers right.
I'm telling the dealer that 6 1/2 months from production to delivery is
unacceptable, especially looking at the corrosion on the engine. He is now
going contact Hyundai and ask them to change the car for a more recent
build. But he was arguing the case that 6 1/2 months was ok, so he is hardly
on my side.
Would anyone agree? What would you say would be a satisfactory time period?
