Goody, I'm in the same boat as you (kinda). I'm also looking for a new ride, but I'm not a student. I posted a maessage similar to yours here a few weeks ago. Everyone here is very knowledgable and has provided a lot of very detailed advise and insight to the ST.
Like you, I've also decided to buy an ST, based on the advise and amount of praise from owners on this site. Just be aware, the ST doesn't appear to be a perfect vehicle, like some of these guys would have you believe. Most of the owners have made up-grades to their suspension due to the stock shocks and rear sway bar being sub-standard. Aside from that, the most common complaint I've heard is that the gas mileage isn't too great. Of course that depends on the model and your driving habits. No one buys a vehicle like an ST expecting to get 30mpg. There are a few other complaints, but those seem to be limited to a few "lemons" which a couple of unfortunate owners have purchased. Over-all it seems to be a nice ride. I'm ordering a XLT Premium.
Good luck.
