I completely agree! The interior is very dated, I don't think it has changed in the last five or so years.
Bose on Cadillacs and Infinitis is not particularly impressive, although whatever Bose they're using on the new XTS and ATS has improved.
Fortunately, I think we will see the much improved 2014 Cadillac CTS in the spring.
Question: did you drive in normal mode or in sport mode (firmer steering)?
