BYD Sealion 7 — new vs used

For a used BYD Sealion 7, condition matters far more than headline kilometres. For a used BYD Sealion 7, the inspection list expands: scan the high-voltage system for stored fault codes, check battery state-of-health if the diagnostic tool supports it, look for evidence of accident repair (panel gaps, fresh paint, mismatched trim), and verify all software updates are installed. A BYD Sealion 7 with full service history at a brand workshop is worth a meaningful premium over one with patchy records.

Negotiating and timing the BYD Sealion 7 purchase

Negotiation on the BYD Sealion 7 happens around the edges, not on the sticker. The brand's MSRP is fairly firm in most markets, but optional add-ons, extended warranty, and accessory packages have meaningful room. Finance offers from the brand's captive lender are often better than third-party quotes, but always compare. Time the purchase around end-of-quarter or financial-year-end if you can — BYD dealers have stronger margins to play with then.

Practical next steps

On a used BYD Sealion 7, ask for the original sale invoice and all service records. A complete paper trail is worth several percent on the asking price.
