First advice I can give you is to test drive the car yourself you will know its suspension and drive.
Car doesnt wobble at 100 even at 120, people here taken it till 160.
Parts will be and should be available at 3S dealership
Car built quality is much better, engine noise is pleasent to hear when you push the pedal. Again you need to test drive it to beleive it.
For tires keep it 13 inch if you want 14 you will be needing low profile tires.
It is best value for money with reduced price.
