Just reached another milestone today, I just rolled 250,000 (as in 1/4
of a million) miles.  88GT 'vert bought new that year.  In major repair
actions so far (less traffic accidents) the car is on its third ignition
module, third fuel pump, third heater core, (note: don't try removing the
heater hoses by pulling), second radiator, second water pump and has had the
alternator recently rebuilt.
   Neat to have goodies I've added over the years, Cobra fuel system, SSBC
rear disk conversion, (with 73mm calipers up front), police kit upper &
lower control arms,  full chassis bracing,(GW sub frame connectors, JBA
upper strut tower & rear shock tower braces, lower K member brace & recently
added a set of MAC castor camber plates to aid in getting the alignment back
to spec.
   Lessons learned, don't ever take your car to Jiffy Lube, when replacing
your heater hoses CUT them off, don't pull, use distilled water when
changing your antifreeze & then leave it in there until it says time to
change it again, changing your oil every 10,000 miles is often enough
(especially if you use a good synthetic), KYB Gas A Just shocks are great
for handling but the GR2's are easier on the back & Flowmasters are the most
obnoxious sounding mufflers ever made.
