I've owned the MG3 Hybrid for a year — I travel a lot, never a dull moment; comes fully loaded as standard, incredible acceleration, etc.

McLaren GT Series

The McLaren GT takes the supercar blueprint and stretches it into a grand tourer, marrying thrilling pace with genuine long-distance comfort and a cabin that’s actually liveable. If you crave weekend escape capability without surrendering driver engagement, this is the car to consider — though it does attract a fair share of admiring glances.
