Should I sell the S2 and get an S4?

[tobodestroyer]

Hi,

I really do like my S2 Avant but I'm rather excited to see that a B5 S4 saloon is actually witthin my price bracket. What are the benefits of an S4 over an S2? Is it really worth it? How do the specs of the two cars compare?

Advice gratefully received.

Thanks
