They would only go to £75 max. I know the Ioniq is efficient but 180 miles without a charge might be pushing it a bit. A short rapid charge along the way should ensure you don't get caught out. Good luck with the collection and journey back.Sounds like we have a similar day! What was their max offer by the way? I looked at the car hire and they charge a lot more to return the vehicle to a different location. Decided on the train instead. I have 180 miles back and really hoping that I wont need to charge it but I have made contingencies in case I do.
