I had the same reaction too when i saw the ad. The seller is a car fanatic and changes car on avg every 6mths.

He sold to me for 81k. He sd his intention was to ask for 86k but his sales agent advertised the wrong price. However, he was kind enough to honour the wrong price. The only downside is it already has 9000km clocked in 3mths. 

from what i know even new car if want to sale 1 day after u drive the price will drop 10k from the purcahse price if sell to car dealer .. bro for safety go to toyota service center ask for the PC service record ..and before u take the car bring it to SC also for check up .. afraid the owner do something with the car eg: change audio player or install auto lock moduler .. those will void ur PC warranty .. without warranty at least have to get discount 30k .. 

Wind noise on Prius C is one of the worst that I've encounter. Even Swift, Vios and even Saga FLX doesn't sound as loud in term of wind noise. The culprit is around the side mirrors. Close to the ears.

did u feel ur PC is going 150km or u only notice when u see the meter ? in my 175km case i was at highway doing 140-150km and a camry 2.2 tail my back i floor the throttle and after few second only notice doing 175km and the camry is at my back about 1 car lenght (didnt high beam) only then i let him pass and the camry owner give me a    up..
