1. Great car.. I'm an accord owner too.
2. I would check the tranny first. ie when shift in reverse or N or to D, does it have a bump ? There are a lot of accord failed tranny.
Out of 3, My 2 friends and I, all from different dealer, in June, July, August of 1999. 2 Have died and mine is still alive. 2 died were cover under extended warranty. There are quite a few bad honda/acura tranny.
3. If you do buy it, change your tranny fluid often.. ie every 15k with Honda ATF only, I'm on the 10k schedule. I seen people using Mobile 1 Sync ATF and tranny became jerky
4. Mobile 1 oil if you can afford it.
