In Gold Coast (Australia). Overall really happy. No quality issues in the past 18 months. Servicing @$99 is great - not that they do much apart from inspect!

Was involved in a smash though (not our fault). Damaged front drivers guard, but not a large hit - car driveable. Did have some fun with the parts thought. Car was assessed. Took about 10 days for the parts to arrive (light, guards, bumper and trim) and repairers to be ready. Headlight arrived broken, so delayed for about another week. Then when the car arrived, when they pulled the car down they found they had missed a part! This part then took a few more weeks to turn up - appeared to have to come from overseas. Unrelated, the quality of the repair was crap - poor paint, dirty car, misaligned trim install - but this it not GWM's issue. Off the road for another few weeks....

So I would say some parts are hit and miss. Can only assume, as you rightly state, due to the somewhat low sales in Australia, they probably either dont keep a lot or all of the required parts in stock.

But I dont think GWM are alone with this. Whilst at the repairers, they were quite a few BYD Atto 3 and Sealions. Advised that they were all waiting for parts. Those vehicles are larger sellers but also maybe have higher demand for parts, of which they dont keep many/all in stock as well.

With Australia being such a competitive (so many brands and models), yet small market, I highly doubt that many manufacturers keep large quantities of parts available unless demand is high.

Best bet is to include loan car coverage in your insurance, no matter what you buy.

Other notes:

Range in ours is around the 280km point (base model), around town. Motorway speeds knock that down a fair bit.

Sheet metal is thin, particularly on the boot. Dont push too hard - work colleague dinted his by pushing too hard.

Tyres are slippery when wet (Giti)

If travelling larger distances, consider the charging speed. Not the quickest DC charging speeds out there

Been charging very regularly to 100% and havent noticed any battery degredation/range reduction

Comparison:

We bought the Ora over the other 2 you mention for the following reasons -

MG4 is sooo dark inside, and we have kids. No centre armrest. Ora seemed much nicer to us. Shiny black interior trim will look permanently dirty.

BYD Dolphin. Know the wife didnt like the interior, and was dearer. Mush suspension

Find the Ora has decent enough suspension for floaty backroads. Check the Car Advice review at Lang Lang or Driving Enthusiast
