Used MG 3 2013-2024 reliability review

What should I look for in a used MG MG3?

When viewing a used car, always follow our used car buying checklist.

The 3's interior is made with plenty of hard plastics that could be susceptible to showing damage, so check the interior for scratches and scuff marks. Make sure the seats and carpets are free of damp, because some door seals on early cars have been known to let water in.

Apart from the standard checks for paint and bodywork damage, you might want to consider where your closest MG dealer is for servicing and spare parts. MG is a small brand, so while it's working on improving its network coverage, finding a dealer won’t be as easy as it would be if you owned a Ford or Vauxhall, for example.
