Hacking other models for your Lego M.O.D. cars
Breathing New Life Into Your LEGO Classic Car Builds: The Ultimate Parts Hacking Guide
Originally by Clark2368 — Expanded and Enhanced
Introduction: Beyond the Plastic
Building a classic car with LEGO can be a rewarding experience, but sometimes you want that extra touch of realism that standard LEGO pieces just can’t provide. This is especially true when it comes to chrome details that can truly make a vintage automobile pop. If you’ve been frustrated by LEGO’s decision to discontinue their chrome pieces and blocks, don’t worry—there’s a whole world of alternative parts waiting to be discovered and integrated into your builds.
The Chrome Dilemma: Why Standard LEGO Falls Short
Let’s face it: nothing says “classic car” quite like gleaming chrome bumpers, grilles, and trim. Unfortunately, LEGO has phased out their chrome elements, leaving builders with limited options for achieving that authentic metallic shine. While silver-colored pieces can work in a pinch, they simply don’t catch the light with the same brilliance as true chrome.
The closest current LEGO alternatives include:
- Metallic silver pieces (flat appearance, lacks the mirror-like quality of chrome)
- Light bluish gray pieces (even less reflective)
- Chrome-colored stickers (prone to peeling and unrealistic texture)
The Art of Parts Harvesting: “Kit-Bashing” 101
This is where the art of “kit-bashing” comes in—the practice of borrowing parts from different model kits to create something unique. This technique has been used for decades by professional model makers and Hollywood prop designers, and now it’s becoming increasingly popular in the LEGO community.
Prime Hunting Grounds for Alternative Parts
1. Thrift Stores & Secondhand Shops
- Goodwill, Salvation Army, St. Vincent de Paul: Regular visits can yield surprising finds
- Independent thrift stores: Often have less picked-over inventory
- Flea markets & garage sales: Can offer model kits for pennies on the dollar
- Estate sales: Particularly good for finding vintage model kits with higher quality chrome parts
2. Online Sources
- eBay: Search for “model car parts lot” or “model kit junk box”
- Facebook Marketplace: Local pickups can save on shipping costs
- Hobby forums: Many modelers sell surplus parts or “parts cars”
- r/modelmakers on Reddit: Members often trade or sell spare parts
3. Hobby Shops
- Clearance bins: Look for damaged kits sold at steep discounts
- Parts boxes: Some shops have bins of loose parts from returns or display models
What to Look For: The Parts Treasure Hunt
1. Plastic Model Car Kits
- Chrome-plated sprues: These contain bumpers, grilles, and trim pieces
- Vintage kits (1970s–1990s): Often have thicker chrome plating than modern kits
- 1:25 scale: Closely matches LEGO minifigure-scale vehicles
- 1:24 scale: Slightly larger but still usable for many LEGO builds
- Manufacturers to seek: Revell, AMT, Monogram, Tamiya, and Hasegawa kits typically have high-quality chrome parts
2. Die-cast Vehicles
- Maisto, Hot Wheels premium lines, and M2 Machines: Feature separable plastic chrome elements
- “Parts cars”: Damaged die-casts sold cheaply
- Dollar store vehicles: Sometimes have usable chrome plastic components
- Matchbox Premiere Collection: Known for detailed chrome trim pieces
3. Specialty Parts
- Old toy vehicles (’80s/’90s): Chrome-plated plastic parts to harvest
- Costume jewelry: Shiny beads or broken components for chrome-like accents
- Holiday decorations: Chrome plastic ornaments can be repurposed
