Depends on how well it's been maintained.

Most any well-cared-for car can go 300K-plus.
A guy I work with has 2 old Pontiacs.  80s vintage.
Changes oil every 3k and adds a colling system flush every 30k.
Both are over 300k miles.
My 91 Camry, to which I was not very caring for its last year, went
291K before roadside fodder.
The current '97 E320 has 133K+ and runs beautifully.
Given everything I've heard, around 200K it may require some
transmission tweaking.
But otherwise it's a great car that should easily last past 250K, and I
expect 350K out of it.
