Car - yup, it hasn't changed much (except for a few scratches and dents) from the way the dealer delivered it 5 years ago.
Bike - I've made some changes, like the bar-end mirrors, engine protector bars and windscreen, to make the bike safer or easier to ride. The TRE and K&N air filter help the bike run a bit better, but I wasn't expecting huge performance jumps. I chose a bike that had enough power and torque for my needs - if I decide to replace the exhaust and install a PowerCommander, that would be to change the sound or improve the milage - I don't need more power. However, this is pretty low on my priority list at the moment - first I'm going to get a mobile GPS system, put a few thousand miles on her this summer, then she'll need a service and new tires.
