First "Real" detail - MB E320

[Shineworks10]

This is my first "real" client. I've done numerous friends and family's cars before but nothing as intensive as this. I showed up thinking it was going to be mostly exterior work but soon find out the client is only concerned with the interior. I haven't done much interior work in the past so I was a bit nervous but decided to give it a try with extra caution. Any pointers or tips on ways I could have done a better job would be greatly appreciated since I am new to this and still learning.
Enough talking, here are some pictures ...

Afters:












I also gave the client a quick courtesy wash. I figure a happy client is a returning client. :biggrin:

Also, what would be reasonable price for a job like this?

C&C welcome...
