Vectra 2003 swap why

Description:

Vauxhall vectra 2003 1.8 petrol motd June taxd 6 month.
Good big family car just done full exhaust inc cat, 2 new front wheel bearings and cv joint. Front coil spring and heater resistor. Drives well remember its a 10 yr old car but really good condition for its age.
Bad points is key fob opens car but doesn't lock it need to use key and there is a small patch of surface rust the size of fifty pence piece on rear wheel arch. Only faults I can find all usual extras e/w, elec mirrors, p/s, cruise control, abs, and all the radio/cd player controls on steering wheel.
