Been using mine for 2mths +. Only complains if the buggy icc n lane keep assist.. Turned off the emergency lane assist. This is a step up from my older prius on terms of comfort n quality of life.
The BYD Dolphin Standard road tax is very cheap - only RM 40. Also, the Extended has some features like sun roof and ventilated seats and powerful motor, which are not really useful. Also powerful motor is the reason why road tax is RM 160. I prefer a long range battery and a "standard" motor so road tax will be RM 40.
