I personally wouldn't worry about other people's opinions, if it is something you like and you can afford it, then do it......
I guess it's a sign of old age but I can't see spending thousands of dollars on mods to a vehicle that is just going to depreciate especially if it's for cosmetic reasons and not function. If the wheels and rims help the performance and handling and you will use it off-road then maybe.
This could open up a can of worms though with decreased handling on pavement, gas mileage, need for better brakes, speedometer/odometer off if tire diameter is changed, clearance issues could lead to a lift kit and on and on.......
