Sounds to me like the head gasket blew when the engine overheated. 97K is nothing for that car as mine has 261K and another on here has 300K so it's really toss up. I can't speak of other issues as mine hasn't had any until now. I'm waiting reply regarding some tranny slippage that seems to be happening now.

I am at 320,000 + miles right now. Still running good, still on original brake rotors, exhaust, struts, engine, transmission, no engine or transmission work to date.

I change oil religiously every 3k miles, including the oil filter. I use Castrol GTX 10W30 regular oil (no synthetics). I use Mazda filters as they are reasonably priced from my local dealer (about $ 5/piece with my discount). The car has had 111 oil changes to date. There is no sign of any sludge in my engine after nearly 334,000 miles. I change spark plugs every 60 k miles, use only the OEM platinum Denso plugs. I get them cheaper from sparkplugs.com. I change plug wires at least every 100k miles. Use only OEM NGK wires. They are available from rockauto.com for about $ 75/set. I change the brake and clutch fluid every 2 years. I change the coolant every 60k miles or so. I use Mazda brand orange coolant. I replace the drive belts and tensioner pulley bearings about every 80k miles. I change the timing belt, water pump, and timing belt idler pulleys every 100k miles. I also replace the valve cover gaskets about every 100k miles, usually when I do the timing belt. I am on the third set of brake pads now, getting ready to replace them.
 
There is one annoying issue with this engine - the EGR flow passages in the intake manifold clog with carbon about every 100k miles and must be cleaned. Otherwise you will get an engine check light with the "EGR flow low" code. The EGR valve itself is bulletproof, as it electrically operated (not vacuum) and it is cooled by engine coolant.
