I was in my local dealership earlier today,
They confirmed new prices are active from the start of next month, I was told the EX is increasing in price by around £800 or so. To avoid the price increase and still get the £250 summer saving, they said they have to register the vehicle by the end of the month, which means finance arranged or car paid for before October.
Not sure which colours are still available in Honda stock, but was told any colours which have the Grey/White interior are unavailable until the next shipment arrives , which should be on the 18th Oct.
I wanted the Grey, and was lucky that my local dealer had one waiting to be registered as a Demo, which I was able to grab, so hopefully I'll be collecting it next Friday.
