I picked up a Infiniti Q45 back in May (2009).
Specs:
90,000 miles
4.1L V8 engine 266hp
Since then all I've done is:
Japanese Cima grill
Hi-lite Xenon headbulbs (disappointing, switch to HID headlight and fog light soon)
K&N air filter
and standard maintenance
This is it when I picked it up:




I'll update with current pics soon
