Okay, I'll try and explain what has happened. 2 weeks ago I noticed an A3 2.0 TDi Sport for £9,850 that I was going to purchase, but I was too slow in deciding and the salesman told me it was "sold". Last week I was searching again for another A3 in similar spec and colour and he found one and sold it to me for £10,850. It was fine until I saw the registration of the car and it looked really similar to the registration to the one that got "sold" the week before, but I didn't think much of it. However, today I went on confused.com to get an insurance quote for my next insurance year and then I saw one of my saved quotes and it was the car that was sold for £9,850 which was the EXACT same car that the salesman just sold me for £10,850! Basically, the A3 I wanted 2 weeks ago was sold and the salesman has just sold me the exact same car for a higher price! I'm an idiot! But what can I do?
