You do know that there's a long list of preventative maintance that they need around 100 K miles.
Also, many times when one is for sale with more than 100 K miles, that preventive maintance has not been done.
Some of that stuff can bite you big time, such as resulting in destroying the engine if not done. So if you buy one with 100 K miles or more, you should be ready to do all that is required, and it will be good for another 100 K miles.
Most cities in the US have one Honda dealer who will work with the online Honda parts purchasing system for customers. You save about 40% with that system, and pick up the order at the perticipang dealer.
Around 100 K miles they need valve adjustment ( extremely important, they are solid lifters and the exhaust get tighter on clearance with use, if it gets too tight it burns the valve, ruins the head, and if the melted valve pieces score the cylinder the engine is ruined ). Also, the intakes get loose and the engine cant take in the maximum air resulting in less power. Get double iridium sparkplugs from rock-auto and put them in after adjusting valves. Valve cover gasket, water-pump, thermostat including housing, both coolant temperature sensors engine and Radiator don't mix them up, they look the same, all coolant hoses and clamps, coolant, serpentine and tensioner with idler, both trany filters there's 2 one in the trany and another either above or inline depending on year, be sure you have the O rings if its the above cvt one, trany fluid and drain and overflow crush-washers, rear end fluid and drain and fill crush-washers, clean throttle body and maf and map sensors you'll need the appropriate sprays and a soft cloth ( microfiber is best ) don't overnighter the sensors screws it's only plastic, flush brake fluid. The rubber gasket between the aluminum Radiator core and the Radiator tanks is sealed in place by crimping. Those gaskets go bad between 12 and 15 years of age, so while it's drained is a good time to replace the Radiator, and it's easier to install the new Radiator temperature sensor, also, new Radiator drain petcock and o ring. If it's a 2015 and has not yet had the improved Radiator mounts installed, add those, pcv valve, engine air cleaner, cabin air cleaner, wiper inserts, oem knock sensor ( if it goes bad the engine will lean out the air fuel mix sooooo bad it will ruin the engine ). Clean away paint below battery ground wire mount, clean battery terminals and check battery. Both O2 sensors, after 100 K they are ready to go bad, and if they do it will ruin the catalytic converters ( there are 2 and they ain't cheap, so replace those O2 sensors ) AutoZone usually will lend you the O2 socket.
All in all, your probably looking at the cost of fluids and parts of around $ 2,500 + / - some and that's using the online discount.
About a weeks worth of work for a DIY mechanic. Watch seversl YouTube about each job.
And after 100 K miles they need aligned with a hunter alignment macheine that measures some angles down to 1/100 of a degree. It makes a world of differance in how they drive. If all the front end parts are OK and nothing needs replaced, that will cost you about $100.00 to $150.00 + tax.
Put a bottle if Red-Line SI - 1 in a full gas tank to clean the fuel injectors asap, and run that tank low, and repeat. From then on about every 15 K miles or so another bottle. Amazon sells a 4 pack for the best price.
Have the alignment shop rotate the tires.
After all the above, they are good for another 100 K miles of very low maintance.
These are very reliable vehicles, but they require maintance every 100 K miles.
