Problems with night vision -- or at the extreme, night blindness -- may be treatable or could be a sign of a congenital problem such as retinitis pigmentosa or other more serious conditions. On the other hand, poor night vision may simply be a sign of an untreated need for glasses, especially if you are nearsighted.

I have a 99 Hyundai Sonata with a transverse V6, and it costs around $300 or so to get the spark plugs changed by the dealer, largely due to the fact that the intake manifold has to be removed, along with all the parts attached to it, in order to get at the rear three plugs (which is a PITA.) But the dealer doesn't charge a separate fee for the manifold removal, they just include it in the price to change the plugs. To do otherwise, well, it's kind of silly. Also, many FWD 4-cylinder cars have transverse engines, and the plugs are a freakin' breeze to get at.
