Used 2012 FIAT 500 Convertible for Sale

I love the retro look and feel, the interior is gorgeous but there are a few issues with my 3 yr old 50,000KM 500C. I bought it 3 years old and a few days ago I've started to hear some creaking noises on the passenger side and back, sounds almost like the plastic on the doors is not put together tightly... I can't figure out what it is exactly but it's SUPER annoying.
