I am thinking of buying a 99 honda accord should i buy it?

From that description it is really hard to tell. If everything is as you say it is, chances are, if its a fair price then it would be a good buy, and the car would last you a long time. But, you never know, so you should definitely get it checked out by a mechanic of your choosing first. It might cost you $50 or so, but it is sooo worth it! Also, if the seller refuses to let you get it checked by a mechanic, walk away.
But in general, the Honda Accord is a great car and if taken care of properly can run well over 300,000 miles with no big problems.

If you get it you will need to change your Yahoo name though, lol. I personally love Chevy's and Honda's!!!
