THE ARIEL ATOM V8 IS AN AMAZING CAR.

I can't decide to fully upgrade this car. If I do, there are 2 reasons why:

• It is the fastest(accelerating) car in the game, so why not upgrade to experience the 1.9 seconds. This open wheeler feels like it has lots of potential, although it already feels fun to drive.
• I want it to compete with cars like the Agera R.

So what do you think? I am a bit short of gold right now(100 gold). Or should I save up for my next car, the 599 GTO.
