First of all - doesn't really matter. If you want a real turbo car, get yourself an Audi S4. Bottom line is, these are sub compact, fun little stylish cars. I got the 1.8 (coming from an Audi btw). Whatever the dealer has, is in your price range, and you like...get it. The LT with the wheel/fog package is an awesome setup. I got myself an LT, minus the wheel/fog package. I personally bought dealer installed fogs for around $350 later on, and I'll get new (bigger) wheels when my stock tires wear down.
Either way, both are the same as far as looks go. The 1.4 is the better choice, but the 1.8 is cheaper and tbh you're not going to notice much of a difference. Trust me, I've driven both.
and BTW - Replacing the timing belt on these engines is simple and cheap, I did check up on that before I purchased my car. Until you had to replace several timing belts on VW/Audi cars, then come talk to me...they basically require the entire front end and car to be pulled apart and can run $1200.
