So I got my 2002 Honda Accord V6 in 2014 it was a gift from my mother. Her husband picked it out at the time. I didn't want it because it of the mileage and problems that came with it. It had a broken rear window and CD player. Also ended up needing the transmission rebuilt within about a month after they took off the tracking device. It also came with a glued on mirror. Since then it has had issues. I have gotten a new engine, a new power steering twice and multiple other things fixed on it. Recently I had the ball bearings fixed a second time. Now my car is like violently shaking when I press on the gas. I have money to get a tune up, which is what the mechanic suggested. After this I am debating on getting a newer car. Is there any suggestions? Or should I continue to try and fix my current one? It is currently at 316,000 miles.
