The tick over is very erratic. This has caused a problem when coming to a halt, the engine will very often die. I have being using the air conditioning to keep the rev's up!
Parcel shelf latch has broken twice.
For the size of engine the car performs well. It has plenty of low down torque, and pulls well right to the rev limiter. The way the car pulls in 5th gear is especially impressive.
The handling is great. Really! It's a vauxhall I know, but it inspires great confidence in the driver. Under steer is well maintained, and over steer is none existent. Compared to the focus, its just as good!
The cabin is very dull, but comfortable. All the controls are easy to reach, and function well. There is loads of room inside.
I have had the same erratic idling problem, with the exact same Astra. I found that cleaning the throttle body makes a huge difference. It only takes 20 minutes, carb cleaner, and a flat head screw driver.
