Who the MG MG3 suits
The MG3 suits a buyer who wants a hybrid at the lower price and is happy with a smaller Hatchback. It has 5 seats, a 293L boot that grows to 938L with the seats folded, and a 10-year warranty on record. It also has the higher ANCAP rating of the two.

Will it fit in the boot?
May fitExample sizes only - measure your item before relying on this.
Volume check only (seats up)
Item box about 166L (57% of the volume). Litres don't describe shape, so this can't confirm a fit.
MG doesn't publish boot dimensions for this car, only 293 litres. Litres can prove something won't fit, but never that a rigid item will - so the best this car can score is "May fit".
Based on the manufacturer's published boot volume.
