Economical car rental/leasing needed (Munich)

Hello to all,
I will need a car for local transport needs for myself from the beginning of March.
I am thinking more along the lines of a Protected content leasing/rental possibility.
If anyone has any contacts or names of local companies except the standard: Sixt, Avis etc then I would really appreciate any information...
You can contact me directly via IN or via email: Protected content
Best regards to all,
Pascal.
