Ok, i apologize. You are right. There is a limit. The three prices in sum cannot be greater than $2,147,483,647. This is the maximum integer range. If they are the value in sum will effectively wrap around ranges and start at -$2,147,483,647 and the system will give you an error because your prices are lower than $150k.
However if you would aquire this much of money it would have the same effect and you would end up with negative money and being smart enough to know that from nothing comes nothing you would not try to host a race.
Also in R4Z' case we talk about a sum of 30 Million Dollars, which is far beneath the range limit and perfectly possible.
