Don't forget that the warranty wiil commence from the date it was registered to the dealer, not the date you bought it so it's not going to be the full three years if that's what the standard Honda warranty is nowadays, may be possible to extend it for a one-off payment.

Is it a genuine pre-reg? Depends on the miles on it. If it's been used as a dealership hack, loan car or occasional demonstrator it's not pre-reg it's used.

Possible rusty discs if it's been standing outside a lot, should clean itself up with normal use.

If it's been standing outside without any possibilty of being aired in the recent foul weather might be damp inside from condensation.

And if course, should you decide to sell it, it's a two owner car, less value but you are paying less money for it-swings and roundabouts etc.

this was originally how i was going to by my new hyundai recently,but my dealer had one unregistered in the colour i wanted and would do it at the same price,so went for that,,

dont forget if you buy a new car you dont know how long its been standing in a field somewhere,,

just check when it was registered and if its done any miles

dont forget these are second hand cars so dont pay more than second hand money,,

good luck,,,,,,,,
