Guys, is it worth to buy Test drive car.

Currently got one proton edar sa offer me CFE preve for discount RM10k from current preve cfe price. But the interest consider as 3.5% since already 6 months

mile age : 1800km ++
minor scatch rear bumper from previous test drive user.
metallic color

Actually its my first time drive preve, very good..but when goes speed at highway around 110km +++ above, I feel a bit shaky holding the steering, maybe need rebalancing, since forte also issued this.

So, it is worth or not buying test drive car??
