Used + crash-replacement workflow (Trek Project One Refresh, Spec discount), how do you build this?

Two workflows, separate Magento implementations:

Crash-replacement (Trek, Specialized): customer crashes their frame, brand offers 25-35% off a new frame replacement to keep them loyal. Magento setup:

• Serial-number lookup field on a dedicated landing page
• Original-purchase verification, check email + order match in Magento order history
• Crash-replacement discount auto-applied via a custom Magento sales rule with a one-time-use coupon code generated per claim
• Ships to LBS for assembly (re-uses the LBS ship-to flow)
• Photo-upload of damaged frame required (anti-fraud)

Used / take-back (Trek Refresh, Specialized’s certified pre-owned): customer trades in their old bike, gets store credit toward a new one. Magento setup:

• Trade-in submission form, serial + photos + condition self-assessment
• Internal pricing tool (manual or auto) generates trade-in offer
• Customer accepts, store credit issued via Magento gift-card / store-credit module
• Bike ships to brand for refurbishment
• Refurbished bikes listed on a separate “certified pre-owned” category with full inspection report

Net effect: cuts net customer acquisition cost ~12% and keeps brand-loyal cyclists in the ecosystem after a crash. Build cost: $12k, $30k combined.
