For “Do I have the same rights buying privately as from a dealer?”, this answer is written for a Northern Ireland user, but some vehicle-registration, consumer-credit and insurance functions operate on a UK-wide basis. The attached sources — GOV.UK - Buy a vehicle: step by step, GOV.UK - Vehicle registration: new and used vehicles, and nidirect - Contact Consumerline — are therefore deliberately mixed where the responsible authority is UK-wide. That is more accurate than forcing every point into an NI-only source.

Practical next step for “Do I have the same rights buying privately as from a dealer?”: do not pay until this point has been independently checked. Save the advert, seller messages and any official or commercial check so you can show exactly what information you relied on.
