Should I buy a 10 year old PHEV?
Should I consider buying a 2014 Mitsubishi Outlander PHEV if it still has its original High-Voltage Hybrid battery as I believe it can cost around £5000 to replace fully fitted?

Although we've not tried this ourselves, it should be possible to check the battery's state of health (SoH) using an OBDII reader. If you're buying from a dealer, it might be worth asking if they can do this for you. From 2016, Mitsubishi provided a warranty that kicks in if the battery SoH drops below 70% within the first eight years/100,000, to give you an idea of how the battery might degrade over time.
