Washed it, claybarred it, machine polished it, blacked up all the plastics, shined the tyres, took about a bin bag's worth of rubbish out of it, leather treated and hoovered all inside, windows inside and out, changed the spark plugs (which took an age as I hadn't taken off the manifold before) flushed and then changed the oil (which took and age also due to not having the faintest idea about the clio).
It was really nice though to spend some time on it having basically thrashed it round without bothering for 6 months.
