One of my daily drivers is a 2003. If you are mechanically and DIY inclined, this car is great value for money.
I recently bought a Reborn 2011 for a friend. The body is fine, but it has mechanical and electric problems that we are working on. Some problems include O2 sensor, EGR, steering rack, bushings, and at least one axle. It actually feels less smooth than my 2003 in it's current condition.
If you are relying on mechanics without any DIY knowledge, avoid these cars. Also, be prepared to set aside at least 15000 a month for repairs and maintenance. Save it, and use it when required.
