If you like it so much & have availability problems in your area, consider a 1st gen Matrix also. The only thing they lack is the roof rack & the hatch opening is slightly less versatile but otherwise interior volume is insane.
I agree w/your points on the 2nd gens. I considered getting a 2nd gen Matrix brand-new but when I realized they didn't have the pop-glass on the rear hatch that was an instant deal-breaker for me. I've used the pop-glass so many times. For example to haul:
numerous 12ft rolls of carpet from the surplus flooring store. They sell remnants for 40 cents a sq foot and many of the remnants they have are extremely expensive carpeting (10+$ a sq ft brands & styles). I used the carpets as area rugs & to cover my stairs
16ft railings with baulasters, newel posts to redo my staircase railings, it poked out the back for 30 miles lol
16ft and 12ft baseboards. had to replace mine cuz previous owner had 2 dogs & a cat that urniated all over the original ones. Was nice to be able to haul these myself
12ft vinyl siding peices. My house had a couple of peices of missing siding from a wind storm when I first bought it, poked out the back
2x 5-drawer full-sized HON filing cabinets. They barely slid into the rear but the top edges of them hit the glass. Popped the glasso pen and voila! Hatch closed & drove home w/the glass open. Insane that i could fit these two cabinets in the car IMO.
Last thing I hauled w/the pop-glass was a 26ft extension ladder. i was borrowing it from my rents & they wanted it back so I stuck it out the back and drove itback to them (~20 miles).
