Hmmm.... I don't know why the Sonex doesn't show up in the list using only those criteria stated. It meets all of them. Yes, I am biased, but it does meet them. ;-)
I looked at building an RV-9, and the build times seemed just a bit too long. As in, vansairforce.com discussion groups were citing 1400+ hours for builders that went so far as to opt for the quickbuild option (and they were still looking at significant time to go), which adds quite a bit of cost.
Avionics and engine are another big budget-buster, but I'll admit that you can make some compromises. As an example, you might find a used mid-time O-235 in the $6,000-8,000 range. Depending on where you live (like under a Class B mode C veil) will require a transponder. My EFIS, comm, and xpnder were $4550. I could have gone monochrome display, and I could have gone with used avionics, but I wanted the compact form factor of the 2.25" avionics. My EFIS has built-in GPS and is color (MGL Enigma).
One thing you might find interesting; if I went with steam gauges, the cost was more for them than an EFIS. That's counting ASI, VSI, ALT, plus oil pressure/temp, fuel, tach, and some type of EGT/CHT. Mid-range quailty & price.
I have 890 hrs build time in my Sonex, and I estimate I have about 200 to go. I estimate development projects for a living, so while I don't expect my numbers to be spot-on, I am relatively confident that it'll be close. I find it interesting that Sonex says "average" build time is about 1200 hrs. Some have done it in 500 (no idea HOW they did that....), some have taken 2000+.
I'm bigger than you, and my wife is about average. We can both sit in the Sonex. Yes, it's tighter than a 182, but not much tighter than my 172. Even in roomier planes like the RV-12, you're gonna want to get out after 2 hrs anyway. (data source: neighbor just finished one and flew it to AirVenture. the RV-12 has LOTS more room than my Sonex, but he was *still* itchin' to get out after 2 hrs.) Of course, the RV-12 is about $63,000; I'll probably have about $33,000 in mine when done.
I'm building mine in 1/2 of my garage. If you have space to store the wings somplace once complete, your goal of having one car parkable will not be an issue. I built the EAA-spec wing rack, so right now only about 1/2 a car could park in my garage. Lots of builders hang them from the rafters, which frees up the space. I simply chose not to.
The Sonex website has a "find a builder" feature. You can type in zip / state / etc and find builders near you. I'd be surprised if other kit companies don't have a similar function. Best bet is to narrow-down your list of kits, then contact a builder and ask if you can see their project. If completed, most will give a ride. I've had at least 10-15 folks call me up out of the blue to see my project over the past 2 years.
