im in the bay area too and with our climate you should run the 20/50 year around. the b. penn oil is a good choice IMO.

where in the bay? are there any service records?

if the valves have not been adjusted in 15k or so miles it is due. you could suggest she take it to the right shop depending on where you guys are for a valve adjustment, the new plugs you note, cap & rotor and a look over by a good independent shop to have it properly checked out.

we call what she needs a PPI... a post purchase inspection as opposed to a pre purchase inspection PPI. if the car has not been well maintained a few things that come to mind besides what I've noted above could be--- brakes, pads? fluid flush? belt(s), fan & AC compressor. gearbox fluid? that could run $1k or a bit more with the oil change required during the valve adjustment and depending on brake system needs. it would be money well spent to make for a safe, reliable car for your buddy's wife.

the oil consumption issues on a 3.2 with those miles on the clock is well documented. she can make sure the valves are adjusted, good oil is maintained and checked regularly and topped off it could go another 100k miles. as long as compression is decent and it passes CA smog keep an eye on stuff and drive it.
