In the near future when my friend's 300TD rolls over to 500,000 miles, he is planning a get together somewhere in So. Cal. I posted photos here:

Not wanting to continue highjacking the thread, I started this one. I am sure he will make an official invite when the time gets closer, and all will be invited. He is planning to drive in the parking lot at exactly 500,000 miles. It may take some extra driving to rack up the miles in order to time it just right, but it will be worth the effort. He may even need to trailer it if the miles get too close, as it is his daily driver. The car has about 496, 2XX on it now. He will be on the road traveling to family for the holidays, so I imagine it will only be a few weeks till the grand event will take place. He is working out the details on the venue, so I will post the approximate date and place when all the details are worked out. Stay tuned!
