I have been a professional mechanic for 28 years now. Over the years I have been a Mitsubishi Master, Subaru Master, Lexus Master and ASE Master. I am only stating this to point out that I am not an idiot or second class citizen. Most of the planet thinks of us "Car People" as stupid. I always do my best to use proper spelling and grammar and very seldom swear. It is embarrassing to me as a mechanic to hear my fellow techs have to use the "F" word 3 to 4 times per sentence. Here are a few of my other gripes.
1. To-- I am going to the store.
2. Too-- I ate too much.
3. Two-- I ate two cheeseburgers.
4. teh It is "the"---not teh.
5. He borrowed me a wrench. No he didn't. You borrowed it--He loaned it.
6. Yous. The word "you" can be singular or plural. It never has an "s" on the end of it.
7. Pronounce your "T"s Example---Where is Mar in----Where is Martin.
8. Where-- Where are you going.
9. Wear-- Wear your new shirt.
10. Were-- You were in the shop.

Hopefully I did not make too many spelling mistakes in that rant.
