Fix and test platform api after Cargurus integration

1. Implement better processing for City
2. Create postcode field and put postcodes there

Examples:

• FY4 5PQ - postcode
• Blackpool - city

The Mease,Hilton, Derby DE65 5BH

• DE65 5BH - postcode
• Derby - city

Unit 2, Woodvale Centre Woodvale Road Brighouse,Brighouse HD6 4AB
