Was this a fair price to pay for this repair?

http://forums.anandtech.com – A family member's car broke down and I footed the bill. I was told that this mechanic has fair prices but let me know what you guys think. Parts paid for: - 4x spark plug seal ($22) - ignition wire set ($30) - value cover gasket ($22) - 4x spark plugs ($10) - ignition coil boot ($60) - cam sensor ($60) I also paid $200 for labor and the total came out to about $458 after tax. Work done was mostly - replaced cam position sensor, removed/replaced spark plugs, seals, ignition wire set, etc. Also cleaned value cover, spark plug holes, and throttle body. (Hardware)
