For anyone interested, these are very reliable cars. My mother had the exact same car and we gave it to my cousin with 240k miles on it and the stock auto tranny lasted him till 250k. I don't recall ever putting anything other than routine maint. into that car in the 180k miles we owned it (bought it used)
I also had a 92 myself, that I purchased from the original owner with 180k miles on it, sold it with 210k and again only routine maint. in the time I owned it. Did not even consider the mileage to be a matter of consideration.
I also have another friend who had 396k miles on his when it lost a tranny and he decided, that due to the mileage, it was time to let her go to the junkyard in the sky.
Very reliable, comfortable vehicle. GLWS
