Joshua Wennmacher uses Lucas Oil products in his demolition derby car

To the leaders in protection:

I am Joshua Wennmacher. I am a demolition derby car driver. This is both a testimonial and a request. I have been driving demolition derby cars for 8 years. The first 3 years I derbied, I didn't use Lucas oil. Each year, I would loose a transmission and my engine would overheat fairly quick. The 4th year, I used Lucas for my transmission and my engine. What a difference it made. I've been using the same transmission for the past 5 years and the same engine for the past 4 years. Each time, they run great and I owe it to Lucas oils.

In May of 2006, there will be a derby event in Davenport, IA. The purse will be atleast $20,000 and the concept wil be different than traditional derbies. The event will be a team derby. Most teams will be compiled of drivers from the immediate area, but I am devising a new team. The team will consist of 5 drivers. I will have drivers from different states driving together. We will have gentlemen from Michigan, Iowa, Illinois, and Missouri. The promoter is allowing up to 20 teams to compete. The promoter even has started contacting national television stations to air the event.

I am offering Lucas the opportunity to advertise and promote their product nationally amongst a target audience that will always have the need for the product. Entry fee for each team is $1000. Depending on the size of sponsorship will depend on the size of graphic on the cars. I should point out that most of the drivers have won "best paint job" awards atleast once in the past 5 years. We are extremely excited about being able to offer you the opportunity and we hope you are excited about the opportunity. I am looking forward to your response.

If this is not the correct place to send the request, please reply back with the correct contact information.

Thank you,

Joshua Wennmacher
