Yeah bro. For 450 you're probably doing pretty good. And like I said. This car is a dream in the corners, (for it's age I mean) and it should be great on gas.
Honestly if I hadn't lost my zeal for this car I would like to hook one up a little. I mean within reason of course. Like maybe making it lighter and giving it some good rubber. I'm pretty sure they don't make a lot of performance parts for that old girl, but like you said it's just gonna be a beater. Just don't give up on her. It's farily likely that she'll need some work, but don't they all.
