Chicken man-
Where ever you apply for and what ever you want to do - do a little researching on the location you are going to apply at. Learn about that particular business - show a sincere interest and be knowledgeable of that location (year they started in business - annual sales - different awards they have won - just anything that can set you apart from another applicant that is looking for the same job - a trip to their bathroom can tell you a lot about a business (ie car dealership). Come in dressed for the part - no trashed jeans/a nice pair of khaki's - a nice golf shirt/no teeshirt - a nice pair of shoes/no tennis shoes. If you got body jewelry take it off - if you have body ink cover it up, if you need a haircut go and get one............too many kids today think for some reason that society owes them something for some reason. Be sincere, honest, and willing to learn and work with a positive attitute. Let your future boss know that you have a goal and what it is - I'm am betting that your goal of fixing up a 280Z will generate a great conversation that will start something like this - - "My buddy use to have one of those and let me tell you about it............"
I didn't mean to ramble but I'm betting if you play your cards right any dealership you walked into would be interested in you and helping you achieve your goals...........good luck......
What part of Northern Virginia are you in? I use to live in Richmond and Culpepper back in the mid 60's.
Remember; plan your work and work your plan!!
