overall just how well it was built.

Interior Space

you never feel like you're cramped.

Power

Having the turbo the vehicle never feels like it has to strain itself to move.

CONS

With the turbo it could have better fuel mileage. With turbos it is recommended to run 94 for fuel mileage.

It’s a vehicle.

CONS
Fuel Economy

Absolutely horrible. Filling up twice a week. The gas Tank is about 14 gallons. The vehicle BURNS through gas.

Power

It’s slow getting out there. 0-60mph is 9-10 seconds. Using Cruise Control it accelerates very quickly to the set speed. Compared to other makes of this year, it’s on the slower side.

Technology and Entertainment

Blind Spot doesn’t detect in the actual blind spot. The Brake Ahead feature detect the color red, so it’ll warn at about anything large and red.
