- Calsonic sticker is normal (thats who they are made by)
- Keep the clutch and learn to use it....it's not hard once you've been driving the car for a while...(is this your first car)?
- Aircon is a weight addition and not needed in a performance car But if you feel you need it, someone will have on in parts section..or at a wreckers like alljap.
- There are a million workshops around, if you do a search you'll find a lot. But in many cases you should be willing to travel, you're better off travelling to a good workshop than going down the road to a dodgy one.
Good luck with your new car.
