Don't think of it as spoiling. Think of it as not being the lame parent.
Parents are notorious for buying you the off-brand thing you asked for. It might be because they're cheap and don't think you'll notice the difference, or it could be that they're completely clueless. Either way, it sucks.
For example, one year for my birthday, I asked my mom for Polo Sport cologne. She bought me Brut. So instead of smelling like a modern-day Greek god, I smelled like a swarthy old fisherman.
Don't be the parent who buys their kid Brut instead of Polo, or in this case, some generic ride-on or push car instead of a luxury one. You'll never hear the end of it.
