Having driven the FHEV, i don’t think you’re missing out too much.
I saw a PHEV at the dealers, the boot seemed to be considerable smaller than the MHEV don’t think my scooter would fit in it. The PHEV and the FHEV I think are 6 speed autos, where the MHEV is 7 and has 3 mode choices, maybe eco-mode might save a bit of fuel, expecting low 30s MPG our current car does less than 30.
I ordered the same (Flame Blue too) last Wednesday (27th April). What is your estimated delivery date on your order form?
Ordered same day as you did 27th, order form states 27th July.
