As everyone has said already, it all depends on how you take dare of your own car. My brother 92 lx crapped out on him at 150 cuz he drove it hard and crazy.
My 96 just hit 110 and it is still running great, no problems at all.
I believe that a civic can actually last forever if maintained properly. I saw an article on Yahoo News a while back of a 4th gen civic that went over 999,999 miles without ever having to pull off the head and do any major work. He changed his timing belt like eleven times and the article listed how many oil changes he had but i forgot. the interesting thing is that since the odometer doesn't read 1,000,000 miles it reset by turning back to 000,000. Honda offered to buy the car off him as a show car kind of thing and give him a brand new civic but he refused,lol.
so anyways, civics can last forever!!!
