1992 Subaru SVX 3.3 13?,000+
1987 F250 SuperCab 460 carb with either 79,000 (unlikely), 179,000 (most likely) or, possibly (but not very likely) 279,000+
1988 Mercedes 420SEL 163,000+
1993 Kawasaki ZX-11D 28,000+
To my knowledge the above are all running the original (reciprocating parts) factory installed motor with the exception of the '88 Mercedes witch had an entire top end rebuild last Fall (heads redone, timing chain, guides, etc.) prior to my acqusition. I would imagine the '73 had this done sometime prior to my ownership, but it's 33 years old! There is really no way to tell with the Ford because the odo only reads 5 digits to the left of the decimal: 179,000 seems reasonable, but it is much harder for me to tell with an older truck that has always been taken care of...
Cheers!
p.s. Heck, the only low mileage vehicle I own is a 2001 Valkyrie Interstate with under 4K.
