Midway Car Rental now carries the eye-catching Mercedes G55 AMG. With a boxy exterior and large 5.4L V8 engine, the G55 has some serious power under its hood. However, slide into the interior of the car and you’re met with the luxurious styling matching that of the S550. With all the convenience features you’d expecting in your luxury car, the G55 is still a fantastically rugged 4-wheel drive SUV.
