go for it by every means, u'll love every piece of it. I suggest u keep it bone stock, interior n exterior. No need to rice it up with body kits or cheap lcds/HIDs. Just get a decent set of alloys in 16".
Sparing the money by NOT ricing it up, go for some performance goodies instead. Which will actually make u feel every minute u drive it.
Regarding royal shield, on silver, I say not to go for it either. Buy some decent MFs and waxes and keep it protected. U'll love looking at the refltive doors in ur side view mirror while driving cz it'll be ur own hands effort.
As for the theft part, I say its Bull Sh*t. Keep ur car in front of ur eyes all the time, don't leave it unattented in lonely areas, use genius ways to guard it and it'll stay with u till death. Trust a very limited amount of people when it comes to ur cars. I have kept 4 corollas in the same way, two are the hottest cakes, GLis and alhamdolillah, No one has ever been successful in putting a mere scratch on their paint. Alhamdolillah, Praise be to Allah Almighty.
Get it insured for peace of mind and tracker, hahaha, remember we had several long discussions on its cons? Yes cons cz there are NO pros of a shitt.y tracker in Pakistan. When u install one in ur car, there will be a LOT of people who'll know exactly where u've taken the car and whats ur daily driving schedule.
