I feel unstable going at moderate speed around a corner. it doesnt feel like it hugs the road. is this because it is base GXE model?

In stability in corners can be from several reasons
The first is the quality of tires in use as all stability feelings are generated by the tire profile, tire pressure and side wall profile and the quality of the tire (for example a 195 -75 r15 tire will feel loose compared to a 195-25r15 tire which has small side wall dimension and so sits better in the corners )
Next is the condition of the shock absorber, worn out , old or not of good quality manufacturer ( shock absorbers are design to take the rebound out of springs and suspension movement and if they are of inferior quality or worn out , instead of allowing the body to roll slowly , it feels like it will fall over )
Next is the use of a stabilizer bar front and rear as this is what keeps the car feeling level on the road when cornering ( if the stabilizer bar is too thin in section it torques to easily and the movement of the center of gravity is not properly controlled and so the body leans too much instead of sitting flat)
Suspension parts , ball joints , struts , steering rod ends , bad rubbers all add to a bad feeling
another reason could be a wheel alignment or loose wheel bearings ( steering tends to dart and feel out of control when cornering)
Many cars are designed with "soft" suspension to enhance the driving experience but this type of suspension will give the feeling of uncertainty when cornering ( like being on a water filled mattress)
To get a cost of the suspension up grade you first have to know what is the reason for the bad feeling
I would suggest a full safety inspection by an accredited specialist suspension shop ( Pedders or the like ) and then a quote on the modifications that will improve drivability and cornering
a job done professionally will be a safe and legal job
