sorry to hear you've had a few issues...

no problems here (knock on wood)...i changed the oil myself at ~2000miles, and raced the car at our local autocross afetr break-in...gonna race it again this saturday at the SCCA test-n-tune event...

coolant level ok, no clunks, a/c is fine...car has a little under 3000 miles now, and is my daily driver...
