Roof top tents are designed to be fitted on SUVs and other large vehicle (better performance and more visually pleasing). We recommend using our tents on larger vehicles, but there are a lot of roof top tents users with small sedans a well. There are several online forums dedicated to this. However, our tents should not be mounted on mini or subcompact cars.
We cannot give you a definitive answer whether the Skycamp or X-Cover will fit your particular vehicle due to the sheer number of racks and vehicle models on the market.
The main requirements are that your vehicle roof and rack have a dynamic weight load of 165lbs or more for the Skycamp 4X, a dynamic weight load of 120lbs or more for the Skycamp 2X and the X-Cover, and that your cross bars be at least 30 inches apart.
You can find your vehicle roof dynamic weight load in your vehicle's user manual, or alternatively contacting the manufacturer.
