I dont think custom bumpers look too bad, they are actually used on most city and county vehicles and still look professional, but noticeable lifts and huge tires would be a turn off to some if this is a sales vehicle. Occasional use I would say don't worry about it, but everyday means that you are bound to find people that think its over the top. If you do a leveling kit, non-aggressive all terrain tires, and bumpers, I dont think most people would notice, and the ones that did would appreciate it.
