There are people on here who will give you horror stories - and think all civics are the same - well they are not
The truth is that Honda's are generally well built and you shouldn't have any issues - as long as you have a good dealer and they have completed all the recalls on the car
The only piece of advice I would giove you is leave the car in gear when parking on a slope then if the handbrake does fail the car still won't move
1st gear if facing up the slope or Reverse if facing down
Your dealer should be able to take care of the rattle you have
Look after your car and it should look after you
Make sure you post some pics of it soon
