Ever sence I bought the thing I have been having toubles. I have only had 1 good memory about it almost 2 good memoys. The first good time is when I first got it started up and I was able to get it up to a high enought RPM and make it idle to take it for a drive around the block. The second almost good memory I had is when we were pulling it to my grandmas house I had to stay in the car and steer it. I was having such a good time steering the car and getting lots of attidion from everyone. I didn't realize that the door doesn't such tight and we went a round a sharp conor and the door flys open I almost fall out and the door miss's a car by 1/2 a feet. But for the past 2 weeks I have been having troubles trying to get the dang thing to run. I was filling pretty good about it tell the guy at auto zone told I should replace the ignition coil for good measures well that screwed me up big time cause now I can't figure out what the heck I burn't out and Im getting fed up with everything on the car being hard to replace and really expensive. Maybe I need to be a little older to have this car and get more auto repair experience behind me. I bought the car for $700 and I bet I can get $1500 out of it easy. I have put about $300 into already. And my parents are no help they just keep telling me I should of bought a car that runs I just don't see the fun in that but I guess there right.
