I am leery of buying my kid anything that could be labeled as prestige car, and it will likely be a used Toyota. Granted my oldest is 8 and I have 5 and 2 year old, so I have a bit of time to think about it. At 36 years old, I still feel 18, so perhaps as I gain experience and years my thoughts will change.
