Dude the Feltzer will treat you right, trust me. I've been driving it for a couple of months now and it has never given me any problems. The big difference between the Elegy and the Feltzer is their weight and traction. Yes the Elegy is faster, but you have to be more precise with your lines when going into a turn, else you risk spinning, and the thing will not get out of a slide very easily once you start to skid.
The Feltzer is more forgiving and responsive but is just slightly slower. Really speed is only going to make a difference on tracks like the commute and route 68. In short the Feltzer will out preform an Elegy on a tighter track, but the Elegy has the advantage on courses with wide, flat turns and longer straights.
Now as Cudwiser put it earlier, it also comes down to the driver. If you know how to control the Elegy, then for the most part it is a very quick vehicle and in most cases you'll find your self up front. But I can do the same thing with the Feltzer and not have to worry about being as careful in the corners.
When making your decision, keep in mind your driving style. Do you tend to make a lot of mistakes and have to correct your self a lot? If so I would recommend the Feltzer. Or do you like to zip in and out of turns right through the apex? In which I would turn you towards the Elegy. Either way both cars are good performers so think about it a little bit.
