The first two things I bought for my car are:
My husband advised that before I should prioritize getting a wheel lock for my car. A few days before my Hyundai Getz was delivered I went to Blade and Handyman to check what they had. Blade had cheaper wheel locks, but they were only good for wheel-to-pedal locking. I decided to get the one at Handyman which cost about PhP500, but was good for several locking features -- wheel to pedal, wheel lock, wheel to clutch, and clutch to break. I read though in an Inquirer.net article that the best way to protect your car is to place the lock on the wheel, so that's what I've been doing.
(2) Car shade
It could get really hot in Manila, so I got a car shade at Blade. I had a hard time choosing. I was torn between Winnie the Pooh, Mickey Mouse and Hello Kitty! I decided to get the one with Mickey Mouse because I felt it had the least "kiddie-look".
