I’m the same. You would have to check everything carefully on a used bike, including hidden things like sweat corrosion under the bar tape if it has alloy bars. But if it’s being sold by a reputable shop, that might give you more confidence in its condition. Being 7 years old I would also check what maximum tyre width you can fit. Ideally you want clearance for at least 28 mm tyres.
