I'm still a very new MG4 owner and have not done lots of miles, and am still getting to grips with driving a new EV, but so far so good.
1/Are there any purchase deals of any sort out there? - I paid list price for my White MG4 SE SR, no deals available, but I did get it within just a few weeks of ordering. I think I was lucky with timing and choice of colour. It came with a granny charger.
2/Lots of posts on here about issues, what are the top 3 that I should look for please before taking ownership? Only issue I have is the options within MG Pilot resetting themselves - I would prefer to have the Lane Assistance off, but it reverts to on. Not a major problem now that I'm aware of it. Seems to be an issue for some but not for others. As a new EV owner, I've yet to fully get my head around range and charging, and had not factored in the effects of the cold weather on performance. It's not an issue for me personally, but worth considering what the actual range might be vs the suggested range. I can't think of other issues, but would recommend having at least a couple of test drives on different days and on different types of road.
3/Any regrets about your MG4 purchase and if so why? Not really. The SE has 4 speakers, which it turns out are all in the front which is a shame. With the Trophy you get 2 in the back as well. That said the sound is pretty good , so I've got over my disappointment!
4/One of my biggest gripes with previous MG ownership was the dealers! MG in Cinderford were great. The sales exec there was very helpful.
5/Is the build quality up to your expectations? I have no complaints. I wasn't sure about the cloth seats, but I think they are also fine and I really like the interior. The infotainment system is straightforward after a good play around with it.
Overall a great looking car, fun to drive and comparatively well priced. Go for it!
