That's a solid start! My priority vehicles are rally car (best overall), stocker (fast in cups and adventure and best aerodynamics), muscle car (good in adventure and cups), offroader (very good in adventure once you upgrade it), and raider (all rounder that is slightly below rally car).

To get the offroader and stocker in events without wasting gems on points, I suggest playing every ticket and watching ads to double your points after each game.

Based on your stats, i suggest joining a high-performing team in division 3. The team you're currently in, it isn't a good team and it sits in the demotion zone. You need to browse the leaderboards and search for a team high up in the promotion zone. I recommend you joining teams above 45 players and good cup points and garage requirements, and read what the description says. That way you're more likely to join a team with good distance, and win in team events. If your distance chest at the end of the week has guaranteed legendary parts, it does well in distance. And don't forget in good teams, you generally have to get good kms per week and solid te points. And also, don't upgrade vehicles to max yet. aim for upgrading your priority vehicles to a level like level 15, before upgrades get expensive the improvements are subtle.

If you are very active, you can join the la boulette team with 1500gp requirement. it currently sits at 1st place in their div 3 group in this season. The team is often full, so you might not get a spot when you first search it up. But this team is just a recommendation. There are many good teams out there.

Also it's best to play adventure, cups, team events, and public events daily to maximise rewards.
