Car appreciation... the aesthetics, the engineering, etc

Also, next week would anyone who is confident with electrics be able to help me install an alarm and potentially central locking? Im thinking about getting this kit: http://www.aseriesspares.co.uk/alarms-/-security/a-sd-alarm-packages/gold-packages-alarm-/-immobiliser-w/-central-locking/classic-mini-mk3-onwards-a-sd-v2-0-alarm-/-immobiliser-w/-central-locking-kit/prod_1172.html
but scared i will cock up

I'll help you wire it but I'm not fucking around with your locking mechanism. I hate those, mine got bent once and I had to open the door from the outside.
