Thoughts on $320AUD for Giant OCR1? (barely used, modded?)

(sorry earlier I posted and i realised my title could be misleading so new one here)

Im waiting on more details (at least a few days later) but what Ive been given is it was

• only used 3 times at most before left in the shed for a few years.

• bought first hand a few years ago (is this possible still given the bike is pretty old 2000-2010 ish?) (theyre giving me more details in a bit when they are back; its their relatives)

• seems to have shimano 105, campognolo wheel tires, SLR saddle

Also this bike seems a little worn out given its apparent condition. The frame looks a bit dirty, and the middle of the handlebar looks a bit off (theres nothing covering it or something). Is this normal and is the price reasonable? $320 AUD (210 USD)
