Re: price dropping !!!
Case in point: in 1987 when I acquired the Judge it was a $600 car. If it had been running it would have been worth more. At 17 it was pretty near the bottom of the depreciation curve and with all of the gas crises the most common "improvements" were to replace the RA 400 with a 350 and the Muncie 4 speed with a Saginaw modified to accept a BW overdrive.
Today being a documented RA 4speed air conditioned car with the Judge option it is worth a bit more.
Reattae (1988-1991) are just hitting the bottom of the curve even though thanks to a number of parts vendors on both coasts and in the middle just about everything is available.
When I bought my 88 coupe in 2001 prices were just starting to drop and I could not justify $10k+ for a 'vert. Here in 2014 I've had three convertibles and just kept the first one I bought which needed more work than the other two.
The Crossfire is still dropping though exceptions may be made for SRTs, eventually they may be equivalents to Grand Nationals (also only available with automatics). I wanted a manual trans which eliminated the SRT but didn't buy for future value, bought for fun today.
So would expect nice coupes to drop into the $5k range (inflation) but the sheer volume of Crossfires produced, 76,000 of them, may slow things a bit.
Just my opinion.
