It's fun for the first few days to few months, then it streaches out. I've been "playing" it for 1.5 years trying to get the daily free gold through ads and I just did the math, if I wanted to unlock the last car to produce it would either cost me over $700usd in the gold to buy or 2 MORE years of the daily gold for free, I've already given close to that. This game is a bad money grab through either up front cash or just stupid amount of adds with no added content. Waste of time.
