vauxhall astra 1.4 swap for zafira (petrol)

Description:

blue Vauxhall astra 1.4 5door petrol, fair condition for age, 84k on clock looking to swap for a zafira as growing family, the astra has the engine management light on, its been on for the last year when I got the car, it gives the error for o2 censor but I have replaced it, had the electrics check and at some point there was an oil leak and its got into the wires. car is NOT in limp mode and this doesn't affect anything on car so I have left it, its been through 2MOT and not been a problem I have all paperwork to prove.
