My missus bought one about 3 years ogo. its the 1.4 also and is a very nippy car.
The things 'I' have had to fix which i found to b common faults were the folowing:
1: The heater may not produce warm or hot heat, this was down to the water valve under the front window (engine bay), it controls the water entering the heater matrix inside the car and often fails. so check the heater is warm. This valve also effected the air con, after replacing it with a new one from ford (£70 and about 1 diy hour) we found the air con was much more efective. its the same item on the KA and fiesta.
2: This just happened so take care, she noticed the dash lights werent working, after i got into it i found it was also the sidelights and tail lights!!! 1 whole week with no visable rear lights on the car. very lucky. The headlights still worked fine, but only as its on another circuit. After taking the dash apart and messing with all connections and relays good old google saved me. The headlight switch is prone to just failing. u cant even take it apart to fix it, so ford wanted me to hand over £100 for one!
i went to the local scrappy for a replacement for £20, but be aware there are 2 types and i was lucky to find the common faulty one as they had al gone, showing it was a very common fault. It doesnt wear out so if it feels worn u proberbly have a good one.
exhausts arnt cheap either, £100+ for a ford factory item, not easy to replace either so if it needs doing dont diy it! 1 whole day it took me. lol
The 1.4 engine does use oil. its just the design so dont worry, but it shouldnt smoke. The only engine fault i know is the cam lobes wear so check its not noisey and rattly.
all the 1.7's we looked at were thrashed or nails thats why we got the 1.4 and its been very good for us both. Visability isnt the best for a first car, but its a girls car alright.
The boot flor can rott, so lift the carpet up in the boot and check it.
ps. watch how u get into it, the front A pillar is very low and u WILL whack your noggin on it. its not nice
