I am searching for a 1970 or so 911 (going to look at one for sale by a nice "fellow pellicaner" on Friday, hopefully it will be the one). I've noticed a lot of people have put 'SC flares' on the rear quarters. Being a newbie, I was wondering what the opinion on these is. I like the stock look, but a friend of mine just mentioned (in his words so forgive me) "they [stock] look gay. They are flat, no bump out at all and are not attractive". Anyway, do the flares affect the value or desirability for one of these older cars? Should I care if it has been done, or is it just preference?
