Sean, the best straight man I've had in recent times!

Just lucky, or DIY without fat wallet fad frills?  Bought the '90 90Q-20V at
90K and the '91 200-20V at 76K, now at 160K and 200K respectively.  Neither
have since seen the inside of a for hire wrench's shop for anything.  Oil
changes of 20/50 or such on sale "dyno" oils done randomly at 10K to 14K
intervals (only in the comfortable seasons).  Orange oil filters changed at
2 or 3X those intervals.  Normally not heavy on the throttle, to acheive 26
to 29 MPG, always regular gas, but do cruise at 85 or so here in NV.  Great,
reliable cars here in snow country, and cheap to own.
