I was shopping a local dealer back in Sept or early October and they told me the cars on the lot were the last they'd have until December. I told them I wasn't going to be in the market until December so that didn't matter to me. I thought this was just a sales tactic but looking at dealers around NorCal the last month or so and inventories have not been replenished. If this dealer is to be believed, we should start seeing more inventory in the coming weeks. Probably 2018's since the 2019 hasn't even been announced in the US.
I do believe there is an uptick due to the HOV stickers. Another dealer mentioned he wasn't too motivated to deal because Bay Area buyers have been sniffing around.
I'm out of the market now (recently turned 16 year old received an old CR-V from his grandfather who no longer drives so I'm sticking with the Altima Hybrid with 177K for a while I guess) but I'm still keeping my eye on the Clarity PHEV. I may decide to pull the trigger but without being in a hurry I might stay on the sidelines and see what other BEVs come out in the next year or two. Saw the Kona at the auto show. Would be a fantastic car for my commute (about 60-65 per day) but a bit cramped in the back for our teenagers. Anyway, good luck to all with this car. Drives like a dream.
