Your new build is running. Now you need the license plates.
While the vanilla experience is brutal, the community has noted that seed 12922607 works exceptionally well with the MSC Editor. Use it only to check bolt tightness. You will discover that the oil drain plug is always 1 turn loose in this seed. Tighten it or lose your engine on the highway.
Also, consider installing the Modern Optimization Plugin. The forest area near the abandoned mansion has a memory leak in this specific build that drops FPS to 15.
Before you even look at the Satsuma, do this:
The "build" part of my summer car build 12922607 new refers to the engine. This seed has a weird quirk: The crankshaft pulley bolt requires 14mm of tightening, not 12mm as the in-game guide suggests.
First, let’s debunk a myth. In My Summer Car, the seed number (12922607) technically randomizes the locations of the stranded van, the gifu, and the junkyard parts. However, veteran players have noted that seed 12922607 consistently spawns the fuel tank straps in the back of the wrecked Fittan instead of the usual shed. More importantly, it randomizes the initial tightness of bolts on the engine block.
If you are starting new, you have a blank slate. No permadeath scares yet. No debt (except to Teimo). Here is your 15-step plan to dominating this specific build.

Let’s be honest: If you’ve clicked on this article, you already know the pain. You know the sound of a loose bolt rattling in the dark. You know the existential dread of hearing a clunk from the rear suspension at 80 kph.
But build #12922607? This one was different.
After 40 hours of wrenching, cursing, and drinking more jug wine than is medically advisable, I finally turned the key on the newest "restoration" to hit the dirt roads of Peräjärvi.
The Build Breakdown:
The First Start (00:03 AM, pouring rain):
The battery was at 11.2v. The fuel pump ticked like a dying clock. I clicked the ignition.
Click. Rrrr-rrrr-rrrr. POP. Cough.
Silence.
Then, a miracle. On the fourth try, the Satsuma roared to life. For three glorious seconds, all four cylinders fired. The fan belt squealed like a stuck pig, but it ran.
The Test Drive (Moment of Truth):
I reversed out of the driveway. Missed the mailbox by inches. Got to the dirt road.
First gear: Screaming. Second gear: Vibrating so hard the mirrors turned into blurry suggestions. Third gear: The death wobble.
At exactly 78 kph, right near the railroad crossing, build #12922607 did what all Satsumas do: It reminded me who was boss.
BOOM.
The hood flew up. The oil light came on. And the brand new alternator? It was now hanging by its wire, spinning uselessly in the wind like a sad metal wind chime.
Verdict:
Build 12922607 is not a car. It’s a consequence. It’s a collection of bolts I forgot to tighten, a testament to the one beer too many I drank while wiring the dashboard.
It now sits in a ditch near the abandoned house. The radio (which works, somehow) is playing elevator music. The engine is smoking.
And you know what? I’ve never been happier.
Score: 5/7 Fleetari repair bills. Would absolutely build again next weekend.

Here’s a proper review of the build “my summer car build 12922607 new”:
Wiring is the number one killer of new builds. For my summer car build 12922607 new, the wiring loom has a hidden fault.
Once wired, fill the brake fluid (DOT 3 – never DOT 4 in this seed or your master cylinder will lock up) and coolant (50/50 mix).
You have built the engine, installed the wiring, and tuned the carb. Now you sit in the driver's seat. You turn the key to position II. The fuel pump whirs.
For my summer car build 12922607 new, the first start requires a specific ritual:
If you hear a "click" but no crank, battery is dead. Grab the spare battery from the shed (the one behind the kilju bucket). If you hear a grinding noise, the starter motor is misaligned—remove and reattach it.
When it fires? Let it idle for 15 real-life minutes. Walk away. Get a drink. The engine needs to reach operating temperature to seat the piston rings. In this seed, the rings only seat if the car idles without touching the throttle for a full cycle.
