I'm in the market and will hopefully buy one soon. I do not see it as an investment, and intend to track whatever car I purchase as often as possible. I wanted something unusual and decent at the track, and it really fits the bill. Plus, it should be fun to drive in the mountains.

In terms of price, I think we're at the bottom of the market for stock examples with low miles only because the supply is running out. I've been looking for about 6 months, and I only saw 2 100% stock (looking at coupes only, no roadsters) that were also under 40,000 miles. I know one sold for $15,250 at a dealer in Ohio and the other sold for $15,500 private party. People that rely on KBB or NADA in pricing their SRT6 for sale are a little out of touch with reality. Even the dealers are selling well below those prices due to low demand for the car. But demand for these cars has always been low, especially when new.

All the other cars I looked at usually had higher miles, and/or some sort of modification. I personally wasn't as interested in a car if it had any sort of modification. I own a highly modified car, I know why people modify cars, and it's not to treat them kindly.

Good luck in your search, roadsters seem to be less likely to be modified, and driven as often. So finding one in good shape at a fairly low price should be possible for a few more years.
