This is a website where poeple register and report problems experienced on their cars. I have provided data about my vehicles to this website. If you look closely you may spot common problems unique to certain vehicles. Also you may find how other owners feel about their car. Also if you're in the market and deciding about two vehicles (X5 or Range rover) this maybe a good site to do some research before you spend your money. Ultimately its upto the individual how they use the data available out there on the internet. I myslef find this site quite useful and i believe this website is a good site that could provide some potential buyers. I have had some very intermittent problems with my car which is still not resolved by BMW. This is one site that could show a giant car company about customer's veiws about their products.
