In no particular order:
1950 Willys CJV35/U USMC Waterproof 1/4 Ton Radio Truck (Jeep) x2 These are both restored and one of them is the most correctly restored example in the world. Has 90% of the original parts including the Radio gear, auxilliary generator, all original sheet-metal except the front floor pans and hat channels. Fairly rare with only 1000 built in may of 1950. Less than 100 still exist, very few restored. Took 10 years of my life to complete these 2 and the fun was the build and the hunt for the rare parts. Now they just sit and should probably go to a museum.
2006 Jeep LJ Rubicon, 4" Lift, Advanced Adapters Rubi-crawler doubler, Alloy rear axles and RCV Axles up front. Currie Steering upgrades and Track bars. Fairly tame build but can do most of what i want to do now offroad. Planning to keep this one for the foreseeable future. Fairly rare example of a fire red LJ Rubicon last year of a 2 year only model, more rare than a Scrambler.
Custom Tube chassis Rock Buggy; Tuned Escalade LQ9 6.0L (Gen III GM LS) power-plant, 43" TSL Stickies, all the good stuff from 2013 when i built it. Kingpin 60, Shaved 14B, 3.8 Atlas 2, Hughes 300M upgraded TH400 5.43 Gears Ouverson rear axles, Alloys up front with Super Joints. Hydro Steering yadda yadda yadda. Dont use much anymore as the rock-crawling has become less interesting as i really don't want to fix it after it breaks. This one is for sale sort of, not trying to hard.
2014 Camaro SS1LE Mostly Stock. I added a Z28 Air box, and its is enough for me. I decided to leave it stock as its appreciating in value from when i bought it in 2017. Has 430 ish HP LS3 with no stupid cylinder shut off crap, Special 1LE only Tremec 6 Spd, 1LE only 3.91 Rear axle with ZL1 outer's and shafts. Pretty Rare car, only made a couple thousand in 2014, White the second most common at 500 or so. This is my favorite car and a long time quest to own a Camaro has come to fruition.
I too have lost interest in working on cars like i used too. I have owned many cool cars and like most of us sold them for another project. I seem to be drawn to rare and less common stuff, makes it more interesting to me.
