A kid point of view: I still remember my green tricycle ... fond memories! Was it new? I don't know. Was it the best tri around? Probably not. Did I care? No.
Now, a parent point of view: It is cool to buy something "snazzy" for our kids, even if they can't appreciate it ... we as parents love it! So, if you "just have to have it" for your daughter, you can afford it, your DH won't be mad, and it will make you happy, then buy it. However, remember you really aren't buying it for her -- she could care less. If you want to be more practical, your options are limitless -- many used plastic and metal tricycles out there ... remember kids only use them a year or two. Personally, I would try and find one of those plastic Little Tyke bikes that have a push handle in the back -- the child "pedals" as you push -- save the back, create a happy child! Believe me, you will end up pushing or pulling ... it is just part of the process (I use to use a broom handle)!!
