The Paint Shop & Parking Garage
Tools & Upgrades - Car Mechanic Simulator 2015
The Paint Shop allows you to repaint vehicles. Eventually you'll end up with repair orders that include a paint job. Do not take these jobs if you do not have the Paint Shop. It requires 5,000xp and $15,000, but does not require Upgrade Points.
Parking is useful, but expensive. The first upgrade requires that you have 9,000xp and $50,000, but it also gives you two of the four possible lots. The second purchase is also $50,000 and gives you the third lot. The third purchase is $100,000 and gives you the fourth lot.
You can't send client vehicles to parking, only ones you have purchased at auction. So as you can see, it's not cheap on any front to collect cars in Car Mechanic Simulator 2015. Without parking, you cannot buy cars at auction. This is one really weak point in the game.
You can choose to go to the parking lot and check it out or you can simply click on one of the cars in the lists and it will automatically be moved to the garage, if you have the space.
