Collect daily car ad data from the following web pages: [login to view URL] [login to view URL] and store the initial data and any change (for instance price change, km change) on a Postgre database. The script should be developed with Python and should not be blocked by the website due to too frequent queries. The information for each car should be stored in a tabular form on Postgre. When the ad is not available anymore, it should be stored with a closing entry as well. The main goal of this project is to track how long a car ad is posted and how frequently the price and mileage changes until the car is sold.

I checked both sites and I can provide you fast and effective Python (Scrapy) spiders that will check all ads and save information into PostgreSQL database just like you want. My script will check any mileage or price change and update database record. Also if will change Ad status to closed if original ad is no longer active. I have worked on similar projects many times before (see my reviews) that's why I'm sure you'll be impressed with my work.
