The essence of the game. It is your job. It is the way you get cash. It is the way you live... Ok, it is maybe not that important, anyway that is the basic activity in the game. Customer comes in and mysteriously says that his car is broken but he needs it for tomorrow. The clock starts right now.
Jobs are generated randomly so you'll have to choose on which car you will work. It seems like there is a group of customers waiting in front of the workshop for the mechanic... Additionally you can take limited amount of jobs in the same time and every one of them is time-restricted. With different difficulty and complexity levels and of course, different payment levels, wise management is the key here.
After whole day of hard work it is time to count your cash and then look around your business. What should I buy to improve my performance? What would attract more clients? You can always just buy more posters on the wall but it is not something called 'great investment' for such a serious business, right?
Speaking of investments. There is a chance for making even more money in the car auction house. Choose wisely, buy used or old cars and renovate them to sell with profit... Or, if you are one of those vintage car lovers, you can have your own collection.
