As has been mentioned, you can find a list of the first 34 orders at Game Guides. With apologies for the long text, the requirements for orders 35-42 are listed here. Most of the orders have additional requirements for replacing the oil or body parts and repainting - these are listed under the Car Status and should be easy enough.

Happy achievement hunting!

There are 42 Story missions - all of them are straight forward with a list what is needed with a little experimentation. mainly engine, suspension or body issues.

A good guide can be found on IGN for the first 34 Missions, the rest of them are quite easy to solve!

Always remember, there is NO need to care about the interior or exterior condition! Save your money on that! :)
