Chrysler 300C SRT8: A quick search on eBay Motors shows mostly 2006 and 2007 models with “buy it now” prices in the low $20K range. Kelley Blue Book puts the price of a used 2009 in good condition at almost $30K, which still isn’t bad, especially considering what a new one would cost you. Base MSRP, new: $47,315.
Dodge Challenger SRT8: The Challenger is the sweetheart of the SRT lineup (but don’t say that to its face), and the retro classic coupe fetches a bit more on the resale market. Most of the eBay auctions will sell 2008 and 2009 models with 10,000 miles or less for close to $37,000, which reflects our KBB findings. Base MSRP, new: $43,655.
Dodge Caliber SRT4: As of this writing, eBay Motors has three listings: two 2008 models at just under $18,900 and a 2009 model for $21,900. All have over 12,000 miles, however, and KBB puts similar 2009s at under $18,000. A little shopping around, and one could be doing front-wheel burnouts for even less than that, we say. Base MSRP, new: $25,470.
Jeep Grand Cherokee SRT8: Based on our experience with this one, we’re not surprised that depreciation isn’t as great as some of the other SRTs to be had. We’ve seen most 2008 models in the high mid-$30K range, with 2007s in the low $30Ks, which is above Blue Book value. Most of these have a few miles on them, too. Base MSRP, new: $44,105.
Dodge Ram SRT10: How could you not love this 10-cylinder, stinking fast truck? We found quite a few 2005 models available on eBay, ranging from about $21,000 up to $28,000, with mileage all over the board. Stay under 20,000 miles and $25,000 dollars, and you’ll be getting the best deal without being unrealistic.
Dodge Viper SRT10: Expect to see sellers asking for high $60Ks for 2008 models, or low- to mid- $50Ks for 2006s, which is several thousand above KBB values. The good new is that most have only four digits put on the odometer. Base MSRP, new: $88,755 before gas guzzler tax.
Dodge Neon SRT4: File under “Keepers,” which will explain why some sellers are asking more than they should for the hot Neon. Look for low-mileage examples under $10,000. We like along the lines of the ’05 with 46,000 miles, with bidding starting at $7500 (“buy it now” for $9500). When shopping, make sure to ask about any modifications the owner may have done.
Chrysler Crossfire SRT6: The oddball of the group, its supercharged V-6 produced 330 horsepower. This one was a bit harder to find on eBay Motors, so we poked around. Most of the prices we saw for examples with reasonable mileage were around $17,000-$20,000. A good deal would be something under that price, with fewer than 40,000 miles on it, but you might have to be willing to go pick it up depending on where you live.
Dodge Magnum SRT8: Another discontinued model, unfortunately, which you may have trouble finding. Kelley Blue Book says a 2008 model with 30,000 miles in good condition is valued at $23,425, which seems to be a little less than actual asking prices of around $26K. If you don’t mind more miles (70,000-ish) or older models, it can go as low as $18K. Like the crossfire, you’ll have more luck finding one at a used car dealer.
Dodge Charger SRT8: This just may be the best opportunity on this list to score a sweet deal. Yes, it may not be as unique or rare as some of the others, but you’ll have a larger community of owners (and sources for spare parts, if you are so inclined). KBB lists an ’07 with 30,000 miles at $26,750. However, several different model years are available, many with low mileage. While many are listed on eBay with “buy it now” prices at or above KBB value, high volume means that, with patience, you can probably score a good one in or below the low-$20K range. Happy hunting! Base MSRP, new: $40,630.
