I would take a long, hard look at louvers for the CR-Z if they would complement.
There might be good value in what I'll call the "Tavarish market." If you're not familiar, Tavarish writes for Jalopnik about luxury and exotic cars that have depreciated to become quite cheap. Like, Camry cheap. A lot of these are vehicles that have not changed much across their production runs, so the eight year old car looks like the one in the dealership.
Here's an example. Maserati Granturismo. You can spend six figures on a new one, or you can buy a 2008 with a few miles on it and sticky Italian buttons for $45,000.
But what if you want to update it, say, with one of those scooped hoods from a late model? http://www.supertweaks.com/maserati/maserati-dmc/maserati-granturismo-dmc-carbon-fiber-front-hood $7,279. According to the forums, the Maserati hood is $12k from a dealer.
Others might be Bentley Continental GT, or Mercedes S and SL class. Well-made, reasonably-priced accessories to update your aging luxury GT or sedan.
