50ish years old, we just bought a 08 Scion xD 1/2008, love it!! Fun to drive, comfortable, getting 31.5 mpg highway, 26 avg. city/hwy. We check mileage against fillups/hand calculating, and found the on board mileage computer was pretty accurate. Lots of leg room, could use maybe another inch of headroom (for me anyway). I'm 6'-3", over 300lbs (of pure muscle mind you!) & am quite comfortable in it though. The automatic, shifts smoothly into gear, digital display on dash also. Engine has plenty of power, undercarriage/engine noise is quiet except when passing etc. but not that big of a deal. Can get a undercoat like Ziebarts Sound Barrier for $179 to help deaden sound.
Plenty of power, handles real well on Interstate, did not get the VSC, not needed, we have good traction/control now in Jan weather. Definitely like the looks, roomy interior and cargo area. Get the Scion floor mat package, nice mats & rear bumper vinyl applique. Pioneer stereo is excellent.
It does need armrests between front seats, that would be nice. Or a dropdown off of the seats.
