How reliable is the Yaris?

[DiCaprio]

I have a 2006 Yaris. Owned it for 15 months and drove about 16.000 miles

Regular maintenance:
- two oil changes
- oil filter
- air filter change
- brake fluid change
- coolant change

Faulty Parts:
- leaking waterpump
- pulley bearing
- loose windows

I feel bad for this car because I believe my racing and off-roading made it fall apart.
The waterpump was leaking and the screws that hold the windows tight came loose,
probably because of extensive vibration (off-roading). I guess that's what I get.
Oh yeah the car needs to pass TÜV Inspection this Friday, so wish my luck haha.
