Repair option

I don't like to use reliability though. It's completely useless for car performance and thus by raising it you build up quite the car handicap. You can't even use research to help you out because noone else is usually going for it because they go for performance. Then it isn't that effective in reducing part needs in repairing the cars anyway.


Then it's an issue of the game manual/explaining how things work, though. At the very beginning you can produce way more parts than you need. It's mostly in the midgame where it can be an issue, but only if you decide it to be one. It all comes down to design building level, and thus amount of design points, versus manufacturing building level but with the big hook that with both at the same level the manufacturing building can't keep up with the demand. So as a manager you have several options:

-You keep the design building at a state you equal out parts needs with production capabilities. You've got a design point   handicap though you have to overcome by partly research and mostly by doing better than the competitors otherwise.
-You make sure you build up a nice pool of parts early on by keeping manufacturing at the max and keep design low to fuel the extra parts needed to go to the max later. (I did that, currently 303 parts left from 350-400)
-You always max the design and rely on getting extra parts with
  -the Ad-system in the App
  -buy extra parts with token by really carefully managing your budget, money and token because obviously you can't buy that       much money now. (That's the plan once my surplus parts are used up)
  -buy extra parts using token bought for real money (My emergency plan B, I do buy a few token from time to time anyway to       help funding the game and then spend (more than) that on liveries and to get the YA drivers just how I want her/him)

Then something was wrong with your starting account. Normally you start with some parts and each race needs only one part per car to repair, exception might be Italy, until you start to build up design. Since Manufacturing only requires two days build time and the first level up is often almost instantly after a race or two it's no problem to build that one level required to about match the needs for a two car team and then further as soon as the team levels for more and more surplus before the initial pool would run out, that surplus then can be matched with design building upgrades according to plans and needs.

It does work but as soon as you're out of the single digit values the effect is really low. It's mostly only able to tip the scales of races where part needs are just above that line to be rounded up.
