It's very easy and inexpensive to add the steering wheel audio controls and cruise control if you buy one without those options. Same goes for the EVIC, as long as the vehicle is equipped with keyless entry. So, don't let those options be a make or break for you. I added all 3 of those options to my 02.
Also added a double DIN Android Auto head unit and rear view camera. Really nice to have in dash Nav, hands free phone, XM, rear camera and Google voice assist. Makes the vehicle feel 10 years newer than it is.
I find the early cloth seats in my 02 firm, but very comfortable on long rides. Heard that the later ones aren't as comfortable. I don't have a sunroof and don't miss it. Liberty's aren't like many other vehicles. You sit so high and are surrounded by lot's of large windows. I normally like sunroofs to make a vehicle "feel" more open and spacious, but I don't miss it in the Liberty at all.
