There was report that they check the upgrade renting on this forum.

When you do it just don't fully upgrade the car than restore. When you full upgrade the count for achievements "Modder" goes up but as you restore discrepancy (between number of actual fully upgraded car and the number that the achievements counted) occurs. Don't do full upgrade.
