My 2005 Corolla LE with 250 miles starts pretty hard sometimes. Several seconds is not uncommon, which is longer than any fuel injected car I've ever owned (92 Camry, 04 Camry, 99 Accord, 87 Bonneville, 89 Sable, 92 Grand Marquis).
I'm not too worried about it at the moment, although I will put some gas treatment in it on the fillup as water in the tank was always the cause when I lived in Wisconsin over the winters there. I was thinking it wouldn't have gotten a chance to get condensation being so new but if its gone through humid Houston (as all Gulf State Toyota cars have) it doesn't seem too far fetched to get a bit of water in the tank.
