C-Class W203: A Closer Look

I don't understand the negative reviews. My only issue is the poor rust protection. However, plastic underbody panels help prevent severe corrosion. Power-to-weight is average but sufficient for smooth driving, even exceeding speed limits.

Pros: Plastic underbody panels prevent significant rust, Sufficient power for everyday driving
Cons: Poor anti-corrosion protection
