You should realise I think after July order books for MY18 open, so you should go check out the facelift before buying the current car, just in case you prefer the facelift as it looks different some prefer, some do not, but power, handling and technology wise the facelift is a big step on compared to current car. Though it will probably be circa 45k with nice options, still crushes any other car for the money though!
Yup aware of MY18. Aesthetics are on par for me, bits I prefer bits I don't - but overall fantastic. I know it'll be better under the hood but as you say price is likely to be higher and im maxing myself as is so not sure I can push much more; also no confirmed dates yet and can see things getting held up and with current contract for my Focus ST3 up in Jan I think it'd be awkward so happy to go for the current model
