I think the problem is because you're buying 330e instead of i, my mechanic always told me to avoid those PHEV since you need to fix 2 types of machines instead of one. Especially battery which for sure would degrade over time, but all in all 10k shouldn't be that much of problem considering the price of the car when new is almost 300k this is still consider a bargain, I guess? I read before replacing all the batteries cell would cost at least 25k for 330e, if you're buying car not for joyride, I think better sell the car and get something more suitable for day to day use within that price, maybe a new car like VIOS which is more reliable? or even secondhand Accord/Camry? Or if you still want to get a BMW maybe 330i would be a better option, I'm about to suggest diesel BMW previously since Europe diesel is actually one of the best but with the current price of fuel it's not that worth it, but when 95 increase maybe the only option left would be get yourself an EV?

Europe car actually champion in Diesel because that's what most of them use in the Europe.
