Yeah, i like older centuries a lot more than the newest one.
You cant really appreciate how wonderful it is to work on a 3100/3400 until you've done it yourself. They're not super hard. They're just aggravating. You spend the whole time asking yourself "WHY?!?" every time you have to take off the next little piece.
If you're going to own a 3100 car and do your own work, do yourself a favor and dont work on anything else. That way you will never realize how relatively stupidly the 3100 is assembled and it wont bother you.
