A sales summary is written to be read quickly. The contract is written to govern the claim. When the two disagree, the form controls the outcome, so the job before comparing offers is to confirm that each summary says what its own form says.
Pull the Form Before the Summary
Ask for the complete contract the buyer will sign, including every schedule, endorsement, and any terms page the form points to. Mark the form's own promise sentence, the sentence that says what the contract pays for or repairs. Only then read the summary, and check it against that sentence phrase by phrase.
Mark the Words That Carry Weight
Summaries tend to use words such as covered, included, protected, and full. Find where the form defines those words. Look for terms such as covered component, wear, pre-existing condition, and the names the form gives the seller, the administrator, and the party that pays. A summary that says included may mean included subject to a list, a limit, a waiting period, or an inspection condition stated somewhere else in the packet.
Build a Match Table
Make three columns: what the summary says, where the form says the same thing, and what the form adds. Rows with an empty form column are gaps. Rows where the form adds a condition are the ones to read back to the seller. Keep one table for each offer you consider, in the same row order each time, so the comparison stays fair.
Decide What the Gaps Mean
A gap is not automatically a defect, and a summary is not automatically wrong. A gap means you have a question to put in writing. Ask the seller which document controls if the two conflict, and ask for the answer in writing. A seller who sends you to a different page for every answer has not resolved the conflict.
