So far as the UK is concerned, I would say you definitely need to declare anything which makes the
car illegal - but most sensible
buyers who want a
car to
use (rather than one to break up for spare parts) would not consider buying an old
used car without a
recent MOT (safety) test certificate in any case.
As more college - age Millennials and
recent grads enter the new - and
used - vehicle market, they are expected to demonstrate less brand loyalty and more wariness of overspending than their forebears, and with good reason: Saddled with student loans, younger
buyers are less likely to make an aspirational purchase and more likely to look for a competitive price on a reliable
car.
