BYD — to Romania, in my area I have to recharge 5 times.
Audi Q5 — to the same place I refuel only 2 times.
At the end of the merry-go-round, if diesel doesn’t rise again, I can say I travel with peace of mind in the Audi — both on price and comfort 😆😆😆. If I switch on the air conditioning in the BYD, I’m totally screwed; for 1,350 km I’d need solar panels just to keep costs down.
But if I only drive around the city and do short runs, all praise to BYD.

My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.
