No inspection claim. No guaranteed appraisal. Modeled ranges and verified facts stay visibly separate.

A LIVE PRODUCT, NOT A PROMPT TEMPLATE

Dream Garage is a published Android product from HyoSoftware. The U.S. web report uses the same structured decision format: identity, Price Fit, evidence gaps and ownership pressure stay separate and reviewable.

WHY NOT JUST ASK GPT?

GPT can explain cars.
Dream Garage runs the Deal Check.

General AI is excellent for open-ended conversation. A used-car decision needs a repeatable sequence: read the listing, verify identity, test Price Fit, expose missing evidence and turn the result into a next move.

GENERAL AI CHAT

Flexible conversation

  • You frame the question and choose the follow-ups
  • The workflow depends on the prompt and enabled tools
  • Source handling and assumptions depend on the chat setup
  • Best for open-ended exploration
DREAM GARAGE

Fixed decision contract

  • Paste a listing, screenshot or VIN
  • The same report structure and evidence gates run each time
  • Observed, modeled and user-entered data classes stay labeled
  • Critical conflicts or an unreadable listing can block a paid deal-specific verdict

QUALITY-GATED DATA ARCHITECTURE

Designed so qualified market evidence can inform future reports.

Today's report uses the submitted listing, official VIN identity, publisher evidence when available and a fixed market model. The data layer is prepared to add recent asking-price aggregates only after every sample, quality and outcome gate can be satisfied.

01

Observe

Capture structured listing facts, extraction method and confidence. Raw page HTML and cookies are not retained; observations store structured vehicle fields and a normalized listing URL.

02

Separate

Keep publisher evidence, user-submitted corrections and qualifying buyer outcomes separate so one cannot silently overwrite another.

03

Filter

Compare exact model years, remove duplicate listings and exclude conflicted records and statistical outliers.

04

Qualify

Only after every gate can an aggregate become eligible to inform a future report, which labels the valuation basis and eligible sample.

VERSIONED, NOT VAGUEEvery report carries an engine version, market-data version and calculation key.

If qualifying coverage becomes available, a later report may use an eligible observed asking-price sample and label that valuation basis. Advertised asking prices are never presented as completed sales, appraisals or guarantees.

This is not live self-training. It describes the data architecture prepared for future eligible aggregates; no individual record changes a market range by itself.
ONE INPUT · FOUR DECISIONS

See what the listing does not explain.

01

Price Fit

Place the asking price against a transparent model-year and mileage planning range.

02

Evidence Risk

Turn missing VIN, title, mileage, fees and inspection access into a concrete verification list.

03

Cost Pressure

Estimate insurance, fuel, maintenance and ownership pressure beyond the sticker price.

04

Next Move

Leave with seller questions, a negotiation range and alternatives worth comparing.
