TheBar said:IMHO low mileage is better unless it sat with dirty oil in the engine for years. The engine/transmission seals tend to dry out quicker when not used but other rubber parts are dependent only on age. For that price if you have to replace seals it is still a bargain. Since you have maintenance records seals may not be an issue. If kept inside my formula is take the age and divide by 2. It doesn't age nearly as fast out of the elements. I bought my 97 five years ago. It had 55K miles and everybody told me I'd have nothing but problems since it sat unused for 10 years. But I checked it out thoroughly before I bought it. I've had zero problems/repairs and use it about 90 days a year. From bumper to bumper everything is still like new and functions like new. You will need to re-caulk everything because caulk ages much faster than rubber. Also change all fluids, engine, transmission, differential, purge brakes, power steering, and radiator. If not you may have problems.
Hi Bar (I've always wanted to raise a bar to a high level, and now I have!),
That's a great experience data point to hear, and I hope that my find turns out to be similarly functional. Yeah, changing out fluids and caulking are de rigueur for me ... heck, at my age, I'm regularly changing out my own fluids and caulking things on a most annoying regular basis, 24/7/365/366! If the photos really are current (they don't contain any metadata, unfortunately), the nearly immaculate condition of the inside and outside of the Challenger (wait, didn't something else named Challenger ... oh, yeah, may their souls rest in peace) strongly suggest that this ship was cared for from stem to stern (getting back to the "barge" nomenclature), including underneath and engine/transmission-wise. It's amazing what just changing the oil and filters on a reasonable basis can do (3,000 miles is nuts, unless you're MHing in a silicate mine!). Sending off fluid samples to a lab can tell you all sorts of incredibly useful stuff about parts wear, especially when comparing them longitudinally over time to look for trends.
Even individual parts that appear to be otherwise identical can be differentiated, occasionally with slightly-to-wildly-different lifespans. Mass production can result in significant variations in products just based on statistical distributions. A friend worked for Varian in the microwave wave-guide division, and they had to make tens of thousands of parts to get one that actually met the specs (and hence it was sold for over a million bucks), with the remainder melted back down to be used to try again. It was impossible to intentionally manufacture parts that met the extremely tight mechanical specs, even if all the time and care in the world was expended on it.
The photo of the roof shows what's likely an aluminum powder bearing (silicone-based?) sealant smeared around the ladder attachment points, etc., that I suspect is not factory-applied. IIRC, the Challengers have a Lauan mahogany layer under aluminum sheeting, that in turn covers an insulating foam core, and is finished off with an interior plywood ceiling base material attached to the aluminum frame. They warn you to not wear hard-soled shoes up there, lest the aluminum get dented, or something else cracks, but, I go one better and have fashioned weight-distributing panels that strap to the bottoms of my work boots.
Thanks for yet-another happy-ending story (well, not that kind of happy ending! ? !) that I can add to my growing collection. The Challengers seem to be pretty well-built from the posts, even though they may not win Prettiest Girl awards from those who prefer half-million-dollar (and often upwards of seven-figures) professional musician concert tour bus conversions.
All the Best,
Jim
