I'm in semi-rural area, between 3 towns of 2000-5000. Also have two large metro areas, maybe 200k people, 20 miles away in opposite directions. I see another Scion XB2 (2008-2015) about once a month. Not the same one. Low seller. I see more surviving first gen XB's, gone after 2007. I have seen only 2 Scion XD's (2008-2014) in total since I bought one 9 years ago. Very low sales. Only 8k a year in the last 2 or 3 years in the US.
For a vehicle that covered the earth for so many years, I can't recall when I've seen a Jeep XJ Cherokee on the road. It took ages to use them all up. And there's that rust thing here.
An extinct make that I continue to see daily in multiples, are the Saturn SL and SL2. Mostly the 2nd gen, but also all the way back. Still serving as commuter beaters 25-30 and more years later. I suppose the plastic bodywork made a difference.
