Well I ran into a deal I could not refuse and traded in the Mustang (and some cash) for a almost like new 1998 Mercedes SL500 with only 30k miles. It has a new top, frame and all, and upgraded hydraulics (the seals fail with time)--here are some photos:
One previous owner from Fort Lauderdale, they drove from there and traded it (and $50,000) at a local high-end dealer for a 2008 SL550, I saw it on the lot and stopped in to "talk turkey", we came to terms and I drove it home.
5.0 L, 32-valve with variable intake timing, 326 HP/347 lb-ft at the crank and a 155 MPH speed limiter; 0-60 in 6.0 seconds. I had it up to 140 today and it definitely had more room to play. It is a slush-box (hangs head in shame) but it's a 5-speed with a very nice shifter. It also will, at WOT and "right out of the box" with no tune, run right up to redline before it shifts.
Not much to customize on it, or performance mods, so I will just drive it--good enough for a geezer like me.
I will continue to lurk about and help as I can...
