2007 was the last year for that body style C-class... Being the last year, it received the whole parts bin in goodies.
The C230 Sport has the AMG style aero kit, and nicer wheels.
No catastrophic issues that I'm aware of. Typical Mercedes "if a sensor breaks, it could be $30 or $3,000" type of stuff but you won't know till you hook it up to Star-DAS.
Pros:
- More seats
- More comfortable
- Better quality interior
- You can now pay for the expensive service at a MB dealership
- Not having to explain "it's really a Mercedes" to people that don't care
Cons:
- Slower
- Mercedes snobs won't be impressed, as it's the cheapest ticket to the Benz show
- Looks good, but won't get you noticed like the Crossfire will
- It will still cost the same maintenance $$$ for a more ho-hum driving experience
Overall a solid car, and I'd rather buy a C-class than a milk-toast econo box from another brand (Although for $20K you could get a NICE 2010 Altima V-6 coupe, but I digress).
