OK over all the way to game handle leveling up and pvp match making is beyond stupid though. It is to your direct disadvantage to gain xp or really play the game for anything more then a few minutes a day. Because all items star levels and skill level are available at all keeper levels you can end up facing someone who is the same level as you but many many times stronger making the match impossible to win no matter what.
Key to 1000ft challenge: 1st day max fuel, max engine, fwd sport, 2 upgrades on the boost. Use the boost where you stall get at least 750ft. 2ed day 4wd and gun with 4 upgrades. Let your self coast down the first hill and don't use fuel while your in the air. Use your boast to get up the last series of hills. Get at least 950 ft. 3ed day max gun and the rest on boost. Coast down first hill. USe all your boost at the crest of the last hill before the boxe hopefully u will slam into the boxs in mid air.
