Vyper has about nailed it. There are a few annoying quirks with the car (tell me what car DOESN'T have any) but it's a pretty reliable vehicle. I'd add in that the ignition switch has been a beast for several people as well but once again, not a real expensive fix if that problem does crop up.
I'm 30 now and as a former auto adjuster as well as someone who had to pay for every aspect of my own car at your age, here would be my concerns for you:
1. Premium gas. You can pay to upgrade and convert it to E85 IF it's around you but that's not saving people a ton either. Gas is certain to only rise and with a mid 20's fuel economy, that bill can add up quickly
2. Because it is a supercharged vehicle and you are a newly licensed driver, insurance is going to soak you pretty well. The redline flies a LITTLE under the radar, but don't think for a second they don't know it's supercharged.
3. If you don't do your own oil changes (and even if you do) this thing takes damn near 7 quarts of Mobil-1 synthetic oil each change. Doing it on your own, this means at least a 40 dollar oil change and you probably don't want to know what a shop will charge.
4. The last big expense that folks your age don't really consider is tires. These are low profile tires which does NOT translate to low cost. Most of the tires made for it are best for summer use which means if you have winters in your area you're going to want a set of snow tires and crappy rims.
I'll throw in a P.S. here and say that we all know what wanting a fast car in high school was like but if you get caught using that speed, those expenses add up quickly too.
That being said, it's a super fun car to drive and if you have the financial and responsibility aspects of my points covered, it should be a pretty solid vehicle for you.
....And now I feel old.
I thought that you only needed to use premium gas if there was a stage kit in it. If the car can run on regular gas stock, but the car has a stage kit, is there any way to remove it?
Yeah, we know insurance will be pretty high...There's not much to do about that...unfortunately.
We will change oil in it, but I didn't know it would cost $40 ever 3k miles or so.
We checked the tires on it and they seem to be pretty good, so that's a plus. Winters aren't too bad here, but if the car has summer tires, we'll probably need all season or winter. I think most summer tires are only good down to like 40 degrees or something.
Now does this car seem like a good deal? My dad thinks if we test drive it, like it, and all that, we will offer $5500 and if they decline, we'll walk. He says that they'll probably end up calling back within a week or so asking us if we still want the car.
