I can't answer what the cost is to repair. But the blue-white smoke is probably oil that has run down through the valve seals while it sits overnight. With 234k (kilometers? miles?) it is not surprising at all that there might be some oil burning. No great harm done in the near future. I had this problem with an 1982 Accord and it was the valve guide seals. When they are worn oil leaks into the cylinder when the car sits and then is burned up after you start the car. I don't think the parts are expensive but unless you are pretty mechanically inclined a professional should repair it.
$1 000 000 Dollars
It is expensive to repair body damage on any vehicle not just the Honda Accord. Reason being is that the parts & paint are expensive and it is a very labor-intensive procedure. The Honda Accord is no more expensive to repair than any other modern vehicle.
Yes, it should.
