Yaris 200k

[SNES]

Hello everyone, hope to be in the good section of the forum.

I currently own a 2004 Pontiac Sunfire (180k miles), which I split with my sister, so transport can be a little tricky, because half the time one of us takes the bus while the other have the car (both going to college).

Thing is, I'd really like to get a Yaris. I do a lot of mileage, always on the highway, and fuel efficiency it's a nice car to get. I have been told that the Yaris uses the same pieces (engine, transmission, etc) as the echo, which is reliable - a friend of mine got an echo with 355k miles on it because it is well maintained.

Downside, my budget can be up to 4000$, maybe 4500$. Only Yaris I have found were around 3500-4500 and had 190k to 200k miles.

My question is, paying like 3500$ for a 190k miles Yaris, which has been well maintained, is it worth it? Or is it better to get one with lower mileage?

Thanks in advance!
