Yea simulation, boo greed
Quality simulation that is fun an challenging. But the purchase system is fouled. There are lots of (incomplete) tracks, all of which are available from the first time you launch the sim, but only if you buy the cars to drive them. There are four base car models with roughly three variations each, none of which have a virtual cockpit. Buying one variation of the each of the four available cars will run you $23-29.
More than that, the prices dont even appear to be present in sim. So if you hit "buy" and enter your password, you might be unknowingly dropping up to $12 on a single car if you forgot to check the in-app prices as they are listed in the App Store. Be your own judge, but practices are a little too shady for me to support. The test drives were fun, but into the trash it goes.
