We could be very harsh on the MG6 here, but telling you that it’ll lose nearly 75% of its value in the first three years of its lifetime is hopefully enough to put you off. As much as we love the romance of re-launching the MG brand time and time again, we think it's one phoenix that'll be best left flapping it's wings in the embers! Step away from that MG dealership.
