Agreed. Beautiful car, but not low maintenance.

Check under front fender and in rear fenderwells for rust or rust repairs.
Test drive at high speed on the highway and check for leaking main seal. Let
it sit and idle and see if it starts to overheat. Test all electrical
components for reliable function (windows, lights, signals, heater fan,
gauges, stereo, etc).  Make sure it idles smoothly.  Check for shifter
bushing slop or worn out synchronizers. Check to see if the driver's seat
rocks back and forth.  Check for TRX metric tires (you don't want those...)
Check A/C function, normal stuff.

Most problems are repairable (just time and $$$); but the rust will never
stop once it starts.  Aftermarket cat-back exhausts can be had pretty
cheaply ($200-ish, IIRC).  Find a Coupe that's cherry but has bad exhaust
system and you might get a steal of a deal.  (Dealer prices on exhaust
systems are breathtakingly expensive.)

If you live in the Rust Belt, find another car to love, or get used to
constant rust repairs.
