Detailed answer — what matters and how to prove it

When you pursue a diminished value claim you ask the insurer (or the at‑fault driver) to pay the difference between what your truck was worth just before the crash and what it is worth after repairs. Insurers commonly reduce or deny diminished value claims by pointing to prior accidents, pre‑existing damage, or a history of repairs. Under Maryland practice, prior accidents do matter — but they do not automatically eliminate your right to recover diminished value. What matters is proof: what the truck was worth before the recent crash, what it is worth now, and whether the recent crash caused a loss in market value beyond any pre‑existing conditions.

Key legal framework to keep in mind

• Statute of limitations — Most property damage claims in Maryland must be filed within the statutory period for actions at law. Maryland’s limitations rules are in the Maryland Code; for timing of filing a suit for damages see Md. Code, Courts & Judicial Proceedings (statutory limitations). For reference, see the Maryland General Assembly statute resources: Md. Code, Cts. & Jud. Proc. §5-101 (statute of limitations).
• Insurance claims handling — Insurers must follow Maryland’s insurance statutes and regulations when investigating and valuing claims. Unreasonable denial or handling of a legitimate claim can raise regulatory issues under the Insurance Article. See relevant provisions here: Md. Code, Ins. Art. §27-303 (unfair claim settlement practices and duties).

How prior accidents typically affect a diminished value claim

Insurers may argue that prior accidents reduced the truck’s market value long before your accident. If the insured vehicle already had a diminished market value because of past collisions, you can only recover the portion of the loss caused by the recent, at‑fault crash — not the prior loss.

What you must show:

1. Baseline value: What the truck was reasonably worth immediately before the crash (a.k.a. pre-loss value).
2. Post‑repair value: What the truck is worth after repairs and any new title or branding (e.g., salvage/rebuilt title).
3. Causation: That the difference between those two values is attributable to the recent crash, not pre‑existing accidents or unrelated wear and tear.

Common insurer defenses and how to respond

• Defense: “Prior accidents caused the loss.” Response: Produce pre‑loss evidence showing the truck’s condition and market value before the recent crash (photos, appraisal, purchase invoice, vehicle history report, prior-condition inspection).
• Defense: “Repairs fixed everything; there’s no diminished value.” Response: Produce independent market evidence: comparable sale listings, dealer appraisals, or a diminished value appraisal that shows market perception and sale prices for similar vehicles with similar damage histories.
• Defense: “Title brands (salvage/rebuilt) from prior events explain lower value.” Response: Show timing and origin of any title brands (vehicle history reports, prior sale or title documents) to allocate how much of the reduction stems from earlier events versus the recent crash.

Evidence that strengthens your claim

Gather documentation aimed at separating pre-existing issues from damages caused by the recent accident:

• Photos and videos of the truck taken before the purchase or before the recent crash (exterior, interior, engine bay, odometer).
• Vehicle history reports (Carfax, AutoCheck) showing dates and descriptions of prior accidents and any title branding.
• Repair invoices and inspection reports from prior repairs, and invoices for the current repair.
• Independent diminished value appraisal from a qualified appraiser who explains methodology (comparable sales, market analysis, and adjustments for prior damage).
• Dealership or trade‑in quotes and listings for similar trucks without the recent damage but with similar age, mileage, and options.

How Maryland procedure affects your case

If an insurer refuses to pay, you can pursue arbitration or file a lawsuit. Keep timing in mind — claims and suits can be subject to statutory deadlines. If you plan to sue, preserve all evidence early and consult an attorney about the specifics and timing of filing. See Maryland’s statute resources above for filing deadlines and consult an attorney about how the law applies to your facts.

Practical examples (hypotheticals)

Example A: You buy a used truck that had a minor fender bender two years before you owned it (documented, repaired, no title brand). You’re in a new collision that causes frame damage. Because you can show the truck’s market value before your crash (purchase records and pre‑accident photos) and a post‑repair appraisal showing reduced market value due to frame history, you can claim diminished value for the portion caused by the new crash. The insurer may offset for prior damage only if they prove the earlier event reduced value.

Example B: The truck you bought already had a salvage title from a major earlier crash. You then suffer a minor accident. Recovery will be limited: the salvage brand already reduced market value significantly, so your recoverable diminished value (if any) is the additional drop caused by the new event, not the whole difference from a clean‑title value.

When to get legal help

Contact an attorney if the insurer refuses a reasonable settlement, disputes causation, or if your claim is large. An attorney can help preserve evidence, coordinate expert appraisals, and advise about statutory deadlines.

Helpful Hints — practical steps to protect a diminished value claim

• Document everything immediately: take time‑stamped photos of the truck from multiple angles before repairs and after repairs.
• Get a vehicle history report and save prior repair invoices and title documents.
• Order an independent diminished value appraisal early; a qualified appraiser can separate prior damage from new damage in their report.
• Collect comparable sales listings and dealer quotes for similar trucks with and without accident histories.
• Keep all communication with insurers in writing; summarize phone calls in an email and request confirmation.
• Watch the clock: ask an attorney about Maryland deadlines for filing suit if the insurer denies your claim.
• If the insurer cites prior accidents, ask them to identify the specific prior event and provide the proof they rely on; challenge any unsupported offsets.
• Consider small claims court for smaller diminished value amounts, but evaluate whether you’ll need expert appraisal testimony — small claims rules can limit that evidence.
