Never tried this before... but I'd like to learn a bit of DIY mechanics. In exchange, I can donate my time to help you with a project... or just some good old fashioned cash.
I live in North Kensington. And I'm flexible. Whenever suits you really.
By the way, I'm 24 and have interests in technology as well as cars. For example if you have a PC that has been running for a while and is now very slow, I can fix that.
