That design is pictured by it's manufacturer as being anchored to roof rack rails. A roof rack would need to be purchased separately since the Mirage does not come with them. Several etrailer photos depict the straps anchored to the top of the hatch on what looks like a Buick SUV. I would not recommend doing that to a Mirage hatch, due to risking either damage to the Mirage spoiler or having the strap anchor slip off because the spoiler interferes.
That strap-on bike carrier retails for $279. etrailer is selling it for $251.99 at this time. That's pretty expensive for what is essentially a one-trick pony.
I didn't know they could be so expensive. That's twice the cost of a hitch designed for the Mirage - one that is easily mounted under the bumper and offers more flexible options.
Here's a hitch and hitch-mounted bicycle carrier combination from Curt that costs less than that strap-on carrier:

Carry up to 2 bikes on the back of your vehicle with this sturdy bike rack from Curt. Anti-sway cradles provide a secure hold. Tilting mast lets you access cargo area. Includes a 2" hitch adapter, anti-wobble hitch pin, and a support strap.
At today's etrailer prices, these two items cost $209.82. That's $42.17 less than the strap-on bike carrier alone.
With a hitch and hitch-mounted bike carrier, you get
- a secure mount underneath the car with nuts and bolts, not fabric straps.
- is less of a theft risk.
- won't damage the vehicle with scratched paint or risk denting the thin sheet metal found on the Mirage.
- allows the hatch to be operated easily.
- allows the bike carrier to be easily installed and removed, in less time than a strap-on carrier.
- does more than a strap-on hitch by allowing other uses such as a hitch-mounted cargo carrier.
With either setup, I suggest getting a set of Air Lift suspension helpers to help carry the extra weight behind the rear axle.
