First of all, I thought you were in love with the S2K.....haha
Personally, I think the CL is the way to go. I am in no way bashing the Integra (I have one), but I think the CL is a step up, a natural progression if you will (had a 97 CL a few years ago - yeah, I know that I took a step back, but a baby WILL change priorities
). If I am correct, you are one of the "older" members of the board and I think the CL would be a good fit for you. Don't take offense, I am 28, so I know where you are coming from.....haha Anyways, as you stated, the CL is a bit classier - if that is a look you are going for, it is a no brainer. I know that the Teg is a blast to drive, and you have done some "fun" things to yours, but I don't think you will be disappointed in the CL - save the auto.
If the CL will only cost you a few grand (and you will recoup some of this in insurance savings), I say jump on it. Also, since it is your dad's you know how it was treated and exactly what the car has gone through (peace of mind is huge IMHO). Plus you will have a car that not everyone and their brother has.....and you can become a card carrying member of the "balla" squad now! lol
How many miles are on the CL by the way?
