Cheap first car for a student for around £850


I'm looking for a first car for myself and have fallen in love with the K11 Micras. I'm trying to find one that isn't completely stock for around the £850 mark. I know I'm asking for a lot but I keep finding rust buckets or ones that are nowhere near me. And I haven't got the time to be constantly repairing one as this will be my only transport.
