Garage Level II Upgrade. Adds test path and repair bench to your garage. The test path is in your shop, through the red metal doors by your repair bench. Here, you can find bad brake parts, bad bushings, shocks and other suspension issues. But not all.

6

Barns. Go to purchase cars in mid to poor condition. 1, 2 or sometimes even 3 cars available. Also random used parts. Note, you might receive a map to a barn earlier than level 6, as a reward for a special customer job.

12+

Junkyard. Go here to purchase mid to poor condition cars and random used parts. Like a very large barn with a larger selection than a barn, typically 6-8 vehicles.

12+

Garage Customization. If you download the (free) DLC, you can from now on customize your garage. Change the appearance of floor tiles, walls, lifters, etc. to suit your mood or the holiday color scheme (Click on the ladder near door #2, in your level III garage.)

18+

Auction. Go here to bid on an assortment of cars in good condition (but not perfect). Usually about 10-15 cars available at an auction, which is much more than you see in a barn or a junkyard at one time.

30+

Garage Level IV Upgrade. Adds paint shop, a third lifter, a welder (to repair car frame) and cleaning / detailing tools (to improve interior condition). Also a battery charger, to magically make old batteries new. If you have the Tuning DLC, you also get a Dyno in a dedicated room. This is the level you have been waiting for: At last you can get cars looking nice, and to 100% condition in all 4 areas (parts, body, interior, frame). Imagine, a $100 interior cleanup job can increase the value of the car by $5000. I kid you not.
