Well, not today, but last week - prepped my '84 Euro TD for it's first major outing this year - to Bill Lightfoot's vintage-car/Pagoda GTG at his estate in Vienna.
First I yanked the crappy PO-installed Asian Blaupunkt with it's aggravating tiny buttons, Vegas-at-Midnite jukebox-display, and unreliable CD-player. Swapped in an older Blaupunkt cassette-radio that used to be in my old 240D - larger buttons, simple dial. Then wired it to work without the key.
(Had no effect on my clock - it still only works after the outside temp gets above about 50 degrees!)
Changed the fuel-filters, checked most of the fluids, washed the car, and cleaned out much of the excess clutter in the back seat & cargo-bay. then installed the factory roof-rack bars. Finally checked the tires just before I left. Car ran well on it's Beltway & Rt-66 outing to the GTG, and I had a great time there.
This was the shakedown cruise to prep for my Virginia Beach trip next week. Still need to check the 5-speed tranny-fliud, flex-discs and exhaust hangers before I go.

Happy Motoring, Mark
