We all have to start somewhere..every garage i have ever took my Z32 to has screwed up my car and it took me learning about it all to fix it.
But more to the point they've been dishonest and led me up the garden path about what they were actually doing and/or needed to be done.
Iv'e already helped quite a few people fix various issues on their Z's from meeting them through buying and selling parts, hence this decision, I won't give up the day job just yet i doubt there is very much money in fixing them - i just enjoy it as a hobby!
If i didn't ask questions i wouldn't have been able to learn & I won't be under taking any work i don't feel comfortable doing.
