Received a faulted car - please avoid.

I bought a car from Auction house Japan and received it with a broken A/C. The damage was the A/C condenser resulting in a $1200 worth of damage and this was never mentioned by the sales person. No report was send with relevant info about the car condition. I asked for explanations and reasons why I received a faulted car and the answer I got was that this was my problem now and the company has nothing to do with this. I even got to be blamed that I broke it. Why would I do this to a car that I already paid? Anyway in a few words, my experience way very bad. Difficult and slow communication, late delivery of the export documents which resulted in my car being left in the harbour for a week, got a faulted car, worn tyres (not mentioned) and finally, no aftersale service at all. Complete disappointment. Not recommended! Please avoid.
