Road-tripping, vintage Mercedes style

I’ve got a roadtrip coming, and I’m psyched about it.  You’d think that after years of traveling by Airstream I might be a little jaded by the thought of yet another cross-country drive, but not so.  The fact that I’m always looking forward to the next trip tells me something good: I like what I’m doing. That’s kind of my ideal for life, to have a sense that most days I am doing what I want to do.

This trip is particularly exciting because I’m taking the vintage Mercedes 300D for its first big highway excursion.  We’ll be going to Palm Springs, California for the Modernism Week Vintage Trailer Show.

No, I’m not going to be towing a trailer this time. I would have brought the 1968 Airstream Caravel, but through a series of events we ended up with 20 trailers in the show instead of the 18 we had space for, and I had to give up my own space so that we could fit them all. So I’m staying in the Riviera Resort & Spa (the venue for the event) and won’t be bringing the Caravel this year.

I have to admit that this time I’ve had more trepidation about the possibility of a breakdown than I’ve ever had towing an Airstream.  On the day of the trip I have to drive 100 miles up to Phoenix, pick up Brett at Sky Harbor International Airport, then continue to Palm Springs and arrive by dinnertime.  There’s not much room for sitting beside the road waiting for roadside assistance.  A 27 year old car with 167,000 miles on it is perhaps not the best choice when you absolutely positively have to be in Palm Springs to coordinate 20 trailers.

But the old Mercedes diesels have a fantastic reputation for running even when they should by all rights be having parts stripped off them at a junkyard.  And with good maintenance, there’s absolutely no reason this car won’t go across the USA and back with 100% reliability.  It’s really a matter of taking care of your vehicle and proactively maintaining things rather than waiting for them to break.

So I’ve had the car looked over twice, by two different mechanics, and asked for specific opinions about potentially problematic parts.  Since my last blog about “The Bug List”, I have narrowed down the remaining issues to only cosmetic and inconsequential items.  I even sprang for a new set of Michelins (thanks for the push, Tom!)

I’ve added a few Mercedes-specific items, like a lug bolt guide tool to help with tire changing, some of the odd “festoon” light bulbs used in interior lamps, and the unusual ceramic fuses, plus a quart of oil. With the addition of my well-stocked Airstream kit bag, I can pretty much disassemble and reassemble half the car, and that should be much more than I’ll ever use on this trip.  In fact, I will be surprised if any of the tools come out of the trunk at all.  I’m just being overly cautious.

One of the fun bits is that I will be running the car on biodiesel for at least the first half of the trip.  Biodiesel is amazing stuff.  It’s made from vegetable oil, so it’s almost carbon-neutral.  Running B20 (20% biodiesel, 80% dino diesel) cuts most pollutants in the exhaust considerably, which is nice since this is a 1984-era car that isn’t nearly as clean as my 2009 version diesel with the built-in chemical processing plant.

Biodiesel is biodegradable and completely non-toxic, so spills or human contact are not much of a problem.  It makes the car run a little quieter, cleans out the fuel system (because it is a solvent), and — best of all — it makes the exhaust smell like vegetable oil (reminds me of making popcorn). The only problems I’ve found is that 100% biodiesel is a bit expensive, currently $3.94 per gallon in Tucson, and  it will require me to replace the rubber fuel lines soon with a different type that isn’t degraded by contact with it.

Well, there’s one other problem, too:  I haven’t been yet able find a reliable source for biodiesel in Palm Springs, so on the way back we’ll have to run dino-diesel.  (UPDATE:  I got the new biodiesel-compatible fuel hoses and am talking to California biodiesel producers about how I might get a refill near Palm Springs.)

See? I’m geeking out about it.  I love it when, rather than mixing business and pleasure, business is pleasure.  It’s not always that way, and in fact I can think of a lot of times I’ve hated what I had to do, but on balance the times like this make up for it.  Just a simple roadtrip — but it’s going to be one of the highlights of February and a memorable experience for years to come.  I can’t wait to get rolling.

    Rich, you need to make friends with the manager at the local McDonalds. You can use the old fryer oil, and make your own biodiesel for a lot less than buying it over the counter.

    Hmmm….the definition of vintage, by the airstream benchmark is generally regarded as anything 25 y/o or >. But by the MB standard, 1971 or earlier is qualified; anything newer than 1972 is faux vintage.

    In the wannabe world, some of the less stringent collectors adhere to the following. If your passenger side rear view mirror does not have the watermark warning, objects may be closer than they appear, you’re in. If you choose to do the Modernism show and CLAIM vintage for a 1983 300D, you should also wear a turban and take a deck of tarot cards.

    Leaving the Caravel at home and opting for a spacious hotel room with amenities is, in a word, not priceless. It is shameful. But I’m jealous.

    I’m really glad to hear you got new tires. Jealous of the stainless lug bolt guide tool – the one that I had with the (long-gone) Passat wagon was cheapo plastic.

    Sitting on my nightstand is a 1991 W124 brochure – I have no need for an old Benz, yet there it sits.

    Have a good trip. We should fly out to Palm Springs for Modernism week sometime to see the mid-century modern houses.

    insightout: I can easily scrub the “objects may be closer” text off my right hand mirror. And if you want to rent my Caravel for the festivities, let me know. You already know my terms…

    My 450sl (a 1974) does not have that dire warning on the right hand mirror, so I guess mine is “vintage”…. Rich all you need to do is replace the glass, and viola! you are good to go as vintage…. now to find a replacement mirror…

    I would be greatly surprised if your Mercedes’ drive train did not go the distance. Accessories, though, can be problematic.

    Enjoy the Fahrvergnügen (from someone who tows with a vintage truck).

    Rich, before you go I recommend you get the book “My Mercedes Is Not for Sale.” It’s the account of this guy who buys an ’88 190 in Amsterdam and drives it through the Sahara to sell it in Africa. It’s quite funny, and will amuse you when that radiator blows and you have to wait a couple of weeks for delivery. No, you’ll be fine, really…
