Skor + stars, not a shoebox
Every on-schedule service earns Skor points and a 1–5 star mark. Shop-verified repairs add points too. A perfect Skor is 100.

Maintenance and Repair Records SKOR
Every oil change should count when you sell the car.
Marrskor turns scheduled maintenance and shop-verified repairs into a 0–100 Skor and a 1–5 star rating. Keep the record. Share it at sale or trade-in. Never miss a service again.

Why owners use Marrskor
A living service record that adds weight at the appraisal desk.
Buyers and dealers already pay more attention to documented care than to a stack of faded receipts. Marrskor makes that record impossible to lose — and easy to trust.
Reminders before things get expensive
Marrskor tracks manufacturer-style intervals by miles and months, then nudges you before oil, brakes, belts, and inspections slip.
Book a network shop in one tap
Participating shops can receive your reminder and offer an appointment. You keep the history. They keep the relationship.
Repairs count — because records count
A documented water pump is better than a mystery car. Minor and major repairs logged by shops add points toward your stars.
Sale-ready packet
Share a clean timeline with Skor, stars, and shop stamps when you list privately or walk into a trade-in. The next owner can inherit it.
Prove the car is yours
Claim a VIN with a plate photo or a registration snapshot. We block the street address automatically. Nobody else can write to that Skor.
Ownership lock
The Skor belongs to the person who can prove the car.
A typed VIN is not proof. Marrskor claims a vehicle only after we can match the VIN to you — without storing your home address.

What we never do
- No public who-owns-this-plate lookup. Federal law (DPPA) blocks that for a consumer app.
- No stored street address. The registration image is masked before it is saved.
- No driver’s license or ID number kept from the card.
- NHTSA VIN decode fills year, make, model, and engine — it is not ownership.
Four steps
How your Skor is built
1
Claim the VIN
Type or photograph the VIN, then prove ownership with a redacted registration photo or a digital DMV credential where your state offers one.
2
Get reminded
When a service window opens, you get a reminder. Book a participating shop or log the work after it is done.
3
Shops verify the job
Network shops record what was done, at what mileage. That stamp is what turns a claim into a trusted event on your Skor.
4
Share it when you sell
Hand the buyer or appraiser your Marrskor report. Documented, on-time care reduces their risk — and strengthens your number.
The scoring idea
100 is earned. Gaps cost you. Honesty pays.
Skor measures how well the car has been cared for and how completely that care was recorded — not whether the car ever needed a part.
| What happened | What Marrskor does |
|---|---|
| Scheduled service completed on time | Full Skor points + 1–5 stars for that interval |
| Service completed late | Partial points. The later it is, the less it is worth |
| Service missed | No points until it is done, plus a temporary penalty |
| Shop-verified repair, minor or major | Points added to Skor and toward your star rating |
| DIY work with a receipt photo | Counted, marked unverified, worth less than a shop stamp |
| Long silence / no new records | Recency fades. A 100 from three years ago does not stay 100 |
Selling or trading in
Bring a score, not a story.
Appraisers already look for oil history, brake work, and whether anyone can prove the car was maintained. Marrskor puts that proof on one page.

Questions
Straight answers
Is Marrskor really free for owners?
Yes. Owner profiles, vehicles, reminders, Skor, and the shareable report are free nationwide. Repair shops pay to join the network.
Is this a Carfax replacement?
No. Marrskor is a living maintenance and repair ledger you and your shops keep current — including independents that never show up on a history report.
Do repairs hurt my Skor?
Documented repairs add points. Hidden problems hurt trust.
How do you prove I own the car?
VIN photo plus a current registration or title. Address is masked. No public DMV owner-name search.
Do you store my home address?
No. The address block is blacked out before the image is saved.
Which states?
Nationwide. Digital wallet proof is added state-by-state (California DMV Wallet first).
