Fair enough. I’d always recommend looking around a bit, especially when there are other similar vehicles available which still have manufacturers warranty. Toyota, Nissan and Hyundai offers 5 year warranty and Kia offer 7.
1/3/18 is when the new vehicles will be on the road, most orders will be placed by now so dealers will know which part ex vehicles are coming in. Out of interest, why are you specifically after a Zafira?
