C30 Decision-making aid

hey people, my oma just has a s40 1,6d (bj 05 summum 22 000km), but now would like to have a c30. what kind of equipment can you recommend (probably a summum again)? what is there for useful additional equipment (the same as the s40/v50 also?) ? what is there to criticize about the car and what is positive? and what kind of engine would you recommend? vllt. the 2,0d? and what will be all new/different for the model year 2009? from when can you order my09 and how long would the delivery period be? generally a new car or even a used one? thank you gruß thomas
