AA Dealer Promise standards typically encourage dealers to supply cars with a reasonable MOT term, and many garages use six or twelve months as a simple standard for retail stock.
In practice, Glasgow dealers may vary. Some will automatically put a fresh MOT on every car, others will top up if there are only a few months left. This should be stated in the advert or confirmed in writing before you leave a deposit.
Use the free MOT checker on GOV.UK to confirm the current expiry date and to see if there are advisory items that you might want fixed or negotiated on before you buy.
