Smart TV for new home (Glasgow)

Hello, I'm looking for a smart TV that you might not require anymore due to an upgrade or similar. I don't want a giant one as I simply don't have the wall space, but something small and manageable for me to put into the boot of a small car. (I say smart TV but I'll happily consider something I can plug a Roku box in, so HDMI port) (Oh and if you have the remote and cables that would be amazing!) Best wishes and thank you for reading! Glasgow, Dumbarton, Clydebank ok for picking up.
