Hmmm I guess your right, If I worked on something once I'd classify myself an expert in the field as well

See below.
Don't get me started on Porsche, I could rant away for pages and pages.

i read both statements and would say that moppie did not say he worked on once, he said that he has worked on one.
there was also no claim of being an expert in the field.... - but he does come from a place of knowledge... main gained around the rally scene... and was also a car mech once. well more than once as in the number - but once in a period of time..
Yip, I have more experiance than the average person when it comes to automobiles.
I have worked for a NZ Lotus and Classic car specialist, I have done all my own work on all my own cars for the past 15 years, and I have spent several seasons as service crew on a Rally Car. I've also been involved in car clubs, and I have been moderating car forums for nearly 10 years.
So while I might make the odd mistake with my geography, when it comes to cars, I do know what I am talking about.
If you like I can bore everyone to death with an explanation of what makes a hair dressers car.
