I'm not normally a nasty, vindictive person.
But I hope he ends up taking his 'reliable' £6k tin shed back to the garage time and time again. Is he getting any options? Looks like the options make it a £7.5k tin shed.
There is no way at all to fully guarantee the purchase of a reliable car.
No tin pot basic lowest spec, no a/c, no elec windows, no central locking nice!
