Re: How to fully upgrade my car?

@Insterestellar If you mean fully upgraded in the sense of filling the performance bars completely, then it just isn't possible on most cars as they can't reach it. Even with max upgrades (5 of 5), only a select few cars can fill even ONE bar. I think the Koenigsegg One:1 has Top Speed rating 10.0 with a full bar, but I'll check the others too, if required.
