I used CarWow and got 2K off the list price, however my experience with the dealer was appalling. I just wished I had gone to the local dealer, I would have had the personal relationship and from what I have heard I would have got a better part exchange.
Having unwittingly bought a dodgy 1.5 tsi SEL Karoq, I'm glad that I used my local dealer - he has been very helpful. I would have hated dealing with this nonsense at a distance.
