Mobile app design needed

Hi,
i need to create an app for automotive. It's something like 'CarMeets' app but with more features.
I need someone who knows about automotive and can give more ideas on how this should be done with a great design.
Map features should be an advanced, for example:
- can see locations of friends in same group you joined
- can see nearby shops that affiliate with carmeets
- events (group can create events)
- etc

Please write 'Automotive' to your proposal so i know you read and understand what i need.
Thank you
