I have a 2009 G37S Sedan with 80k on the clock. Thus far, the only maintenance has been standard wearables (fluids, brakes, new belt, filters, tires), though the AC compressor was replaced under CPO warranty around 2012.

At around the 10 year mark, I'm trying to get ahead of what might break. Trying to avoid unscheduled downtime.

1. Cooling system-- what are the common failure points? Should I go ahead and replace thermostat, cooling hoses, reservoir, etc? Radiator? Anything plastic/rubber probably needs to go within the next 5 years.
2. Exhaust-- cats seem a common point of failure, should I plan to go with a high flow cat?
3. Suspension-- while it drives fine now, I'm assuming shocks will need replacement within the next year or so. Other areas? endlinks? Shock mounts? Anything plastic/rubber within the next 5 years?
4. Driveline-- motor/transmission mounts?

Other notes: I live in Texas (high heat) and most miles are city/stop and go traffic. Car is garaged and otherwise treated well (two owner).

Thanks for the insight!
