Buying 2nd Hand Car - Accident Damage

[Pepscobra]

Hi Guys,

I put down a deposit on a secondhand car for the wife last week.
Car looked good at first glance, but being a relatively new car (2013) I needed another opinion, so I arrange a Redbook vehicle inspection via carsales.com.au

Inspection was done this morning and the vehicle inspector called me to tell me the vehicle generally checked out ok, but it had been involved in an accident. Rear right side repaired/resprayed and both right side doors removed.

I'm a bit angry that the seller didn't disclose this to me. My deposit wasn't subject to the vehicle inspection, so if I walk away I'll lose it. When I called the seller back and asked him about it, he said that it only happened 3 months ago. I asked for my deposit back, but he said no, so may get messy.

Two questions;

1. Should I even be concerned about the repair if it was done properly under insurance with a warranty? Seller has told me he will provide all paperwork on the repair with the vehicle.
2. Do I have any recourse to get my deposit back? Its only $500, but with a young family to feed, that' a lot to me.
