pro: you'll love the results, con: you'll never finish
In a seriousness, once you start you will never finish. After one thing is done, it's on to the next. You will love the results you get, just make sure to plan ahead and if you are wanting to do a certain thing, stick with your plan. Don't go cheap because in the end it will cost more. As far as driving , etc.. I have a 4" and have had no problems to date. Just follow the instructions, don't rush, make sure ALL the parts are there before you start and ask if your not sure. Good luck.
