How do I increase my Gran Turismo 7 Collector Level?
To increase your collector level, you’ll need to collect cars!
Very specifically, you will earn one Collector Point for every full 1,000cr value of any car you buy or win. If you buy or win a car worth 20,000cr, you’ll get 20 Collector Points, but if it’s worth 19,999cr you’ll only get 19 points. The number of points you need for each level increases, with 1,510 points — equivalent to a garage worth 1,510,000cr — required to hit level 10.
Increasing your Collector Level gives you access to better tuning parts and to new events in the Mission Challenge section.
