33/39!
I'm very happy with that as in 2013 I literally wouldn't have been able to name 1 of 39!
I decided to learn a bit about my car after getting reamed by a mechanic for a job he 'had' done which I discovered he hadnt even touched. I had a gutful of being ripped off and made it my business to learn a little as being ignorant about it was costing me thousands 8.(
Basically in 2012 when I lifted the bonnet it was like me staring into a bowl of spaghetti, I had no idea what was what as it was all equally confusing!
