Thanks for the feedback guys. Really appreciate that.

Don’t mean to disagree but does that mean the total savings of ~35k ie. 110k as compared to new unit 145kish is not at all justified??? Taking into consideration VW poor resale value, I was thinking I may be able to cushion some of the highest depreciation which happens to be in the first few years of ownership.... hmmm...

Btw I thought there are 5 years warranty so there is no issue

I bought demo unit 2014 mfg Polo Sedan on year 2016 with 168 km mileage, at MyVi price.
Sounds great right? Well, upon deliver, the engine bay has loud vibration sound during reverse, radio signal bad reception which I need to deal with VW SC. First issue quickly rectified but 2nd issue radio poor reception had gone numerous visit to SC on 6 months span, complaint, left car over 1 week twice for inspection, and email to VGM. End up they preferred to blame the fault on I installed reverse camera(which is after some time), which causing interference on common ground. Bullshit, I fixed after visit workshop outside, which found the fault on corroded antenna PCB under the base...
Things does not end there, I got absorber faulty within 10k km, which they said absorber only covers on 6 months/10k km, but my demo car already passed 6 months and not entitled for warranty. Arm rest button, ECU bracket broken on 20k km, which also cannot claim due to these are wear and tear warranty 6 months/10k km only.
So moral of the story? Don't buy demo car that has passed 6 months/10k km. Majority of their warranty claimable items falls under 6 months/10k km including absorber, interior accessories, brake disc and pad etc etc...
