I have a pre-price increase Model 70 RWD on order for delivery in September, list price was $70,000 before options, tax credit and destination fees. My DS informed me that I could essentially 'downgrade' to the S60 by paying the $500 change fee, since my car isn't yet in production. So, my net savings would be $3500, since the list of the S60 is $66,000. Thoughts on saving the $3500 (or using it to get more options) vs. keeping the order as it is? Thanks for your opinions.
