+# RR3 Community Server - Complete Game Systems Implementation
+
+## 🎮 NEW: Full Game Progression System
+
+Based on analysis of the decompiled RR3 APK, I've implemented a comprehensive progression system that mirrors the actual game structure.
+
+## ✅ What's Been Added
+
+### 🏎️ Car Ownership & Garage System
+- **Purchase cars** with Gold or Cash
+- **5 starter cars** across all classes (C, B, A, S, R)
+- **Car database** with manufacturers, performance ratings, pricing
+- **Garage management** - track all owned vehicles
+- Full inventory system for player garages
+
+### ⬆️ Car Upgrade System
+- **5 upgrade types**: Engine, Tires, Suspension, Brakes, Drivetrain
+- **Progressive upgrades** - increase Performance Rating (PR)
+- **Cash-based economy** for upgrades
+- **Upgrade tracking** per vehicle
+- Performance improvements visible immediately
+
+### 📈 Player Progression & Leveling
+- **Experience Points (XP)** - earn through racing
+- **Level system** - gain levels every 1000 XP
+- **Level-up rewards** - 10 Gold + 5,000 Cash per level
+- **Reputation system** - track player standing
+- **Currency tracking** - Gold, Cash, XP, Reputation
+
+### 🏁 Career Mode Support
+- **Career series tracking** - organize events by series
+- **Event completion** with star ratings (1-3 stars)
+- **Best time tracking** per event
+- **Star-based rewards**:
+  - 10 Gold per star
+  - 2,000 Cash per star
+  - 100 XP per star
+- **Progress persistence** - resume where you left off
+
+## 🔧 Technical Implementation
+
+### New API Endpoints (`/synergy/progression`)
+
+```
+GET  /synergy/progression/player/{synergyId}
+     - Get complete player profile (level, XP, garage, career progress)
+
+POST /synergy/progression/player/{synergyId}/update
+     - Update progression (add Gold/Cash/XP/Reputation)
+
+POST /synergy/progression/car/purchase
+     - Buy a new car (Gold or Cash)
+
+POST /synergy/progression/car/upgrade
+     - Purchase upgrades for owned cars
+
+POST /synergy/progression/career/complete
+     - Complete a career event and earn rewards
+```
+
+### New Database Tables
+
+#### `Cars` - Vehicle Catalog
+- CarId, Name, Manufacturer
+- ClassType (C/B/A/S/R)
+- BasePerformanceRating
+- CashPrice, GoldPrice
+- Available flag
+
+#### `OwnedCars` - Player Garage
+- UserId, CarId, CarName
+- PerformanceRating (current with upgrades)
+- UpgradeLevel (0-5)
+- PurchasedUpgrades (comma-separated list)
+- PurchasedAt timestamp
+
+#### `CarUpgrades` - Upgrade Options
+- CarId, UpgradeType, Level
+- CashCost, PerformanceIncrease
+
+#### `CareerProgress` - Event Completion
+- UserId, SeriesName, EventName
+- Completed, StarsEarned (0-3)
+- BestTime, CompletedAt
+
+#### `User` - Extended Fields
+- Level, Experience, Reputation
+- Navigation to OwnedCars and CareerProgress
+
+## 📊 Seeded Data
+
+### Starter Cars
+1. **Nissan Silvia Spec-R** (Class C)
+   - PR: 45 | Cash: $25,000
+   
+2. **Ford Focus RS** (Class B)
