Forgot to add this to the last thread, just an observation. Don't want to ruffle any feathers here but over the past 3 years, but when I first registered on this forum and started looking for an R129, it strikes me that the folks who posted back tend towards undervaluing them. In other words, almost everyone here has bought an R129 used at some point because they just loved these cars and had to have one (or two, or three maybe) yet when I have posted about buying one and asked about values, the replies almost always come saying that I would be paying too much for the particular car, the prices or soft, you should be able to find a good one for a lot less, etc.
Why is that to do you think? Shouldn't you guys be saying - hey these cars are worth more...
Unfortunately the market is what it is. A lot of R129 owners are upside down on their cars, mainly because (and I'm making assumptions here) that they paid what they felt was a fair price for the car. That being said, the retail market for R129s has been soft for some time - just look in eBay listings, for example. Better yet, if you look at prices around your immediate area on venues such as Craigslist, you'll see this as well.
There are a lot of these cars on the road, most people don't consider them terribly distinctive like most MBs of their vintage, and detractors often compare them with far more plebeian cars, like Mustangs.
Wander around in the R129 forum and you'll see what I mean.
I bought my R129 a little over a year ago for $5,000. It's a 1997 with 73k on the clock at the time. It needed top cylinders badly, but was otherwise in good condition, save the corroded stock chromed wheels on it. After I got it into 100% condition a few months ago I put it on Craigslist locally for $7k just for fun.
The extent of the responses I got were lowballers offering me less than what I paid for it. I expected a few, as that's the nature of Craigslist, but it was a regular theme of the potential buyers, or so it seemed.
If you have one of the special editions it's got more value, but the regular models have been soft price-wise for some time.
