Does my car have a lot of miles?

I have a 2000 honda civic 2 door coupe that I bought off a friend for 1500. It has 185k and the only problem is that a bearing in the transmission vibrates but that's not a big concern. He used the car as a daily commuter so I'm wondering how much longer until the car dies out? Is 185 a lot?

Get his maintenance records and take it to a tech for an inspection.
after he sees what he needs to see, you can get a real answer.
Then you can see the future plan and budget, or decide whether to keep it.

No normally 300k, but some fail before that

ITS ON ITS LAST LEGS.

Depends on how well it's maintained. Have a pre-purchase inspection. For a well maintained Honda, 185,000 miles is just halfway, they normally reach 300,000 miles.

If it's mostly hiway miles, that's not bad for the car. But if commuting is thru city traffic, it beats the heck out of car, stop and go running is verr hard on cars. But japanese cars---toyota and honda---are legendary at lasting.

$1500 for a friend"s 2000 Honda? Hmm… Could be okay.
Does everything seem to work on it? Is inside trashy or in good condition. If car looks good inside and out, that means the car in general was taken care of.

185K is a lot of miles, but the Honda can go for while longer, easily up into mid 200's. I bought 1991 Geo Prizm (fake Corolla) with 100K miles on it, and drove it up to 260K miles in 10 yrs, and engine and tranny were still working great. But body was wearing out.

But your tranny is going to need work on it soon. The vibration is sign that something is wearing out, and eventually it'll go. If it seems okay, then keep driving. But usually, a vibration in tranny will work it self out into rest of car, even if it's just that YOU feel it while you drive.

So basically, it sounds like it might be good deal. But you'll eventually have to deal with the tranny.
One good suggestion from personal experience.

When you change out motor oil, go to auto parts store, get some Motor Flush. Quart can, you can use just half of it at a time.
Add it to warmed up engine just before you change oil. What it does is melt or thin out old oil deposits that might be inside. In just a minute, you'll hear the motor run easier, smoother. Don't have to run it long, maybe 3 or 4 mins. Then have oil changed out. Will help engine to run better, and longer because it doesn't have old gunk in it. That kept my prizm going up to 260K miles and beyond. If you have garage or Walmart change your oil, just add it to engine before you hand it over to garage. It'll all drain out when they change the oil.
