I think some styles look really good - a bit like wheels, some look awful and don't suit the car, while others I think do. I had some fitted when I bought my Rangie 5+years ago and have never regretted it - there were original Land Rover accessories including running boards, but I had a pair of chrome / black ones fitted to my black Rangie and they look just right. Garage said they were easy to fit and bolted straight on as they were made for the Rangie. They've lasted over 5 years and have spared the Rangie from a number of car park dings and damage from a piece of rock flying up and hitting the edge of the running board, breaking the end piece, rather than the Rangie's rear side panel. My Rangie doesn't notice the weight and she gets over 20mpg despite being a 4.6!
