TIP: split the stats-box into two boxes, 1st containing the stat-names and 2nd containing the values, and alignment issues will be a thing of the past.
you need to work on the input-handling, too often have I suffered from the steering locking up at completely random moments (happens even at minimal/medium speeds)
I just had an idea: why not give the buy-bars the following colors? red for unbuyable (dulled when partial buy is possible), yellow for partial buy, green for full buy.
I've updated it with a reset button, thanks.
