This site offers the general public a chance to buy damaged Boats and motorcycles that are for sale by insurance companies. It is basically a reseller site since the boats and bikes are not ours. They are owned by insurance companies and are sold by a large public company. We just earn money off of adsense not off of the sale of the cars.
I spend about an hour a day on the site. The only overhead I have is hosting but if you are outside the US you might have a little more such as cost of internet access which can be as high as $100 a month. The site made $662 last month from adsense. I didnt have GA installed correctly for a while and really last month was the first full month of correct stats but the site has had steady traffic for a while but the way flippa uses the api and averages out the traffic it made it look like it has lower traffic but most months it gets about 10k visitors.
The buyer will have access to the cars which are auto updated on the site. All I do is market the site which I do on several different sites such as craigslist, ebay motors, backpage, ect. The value in the site is in the marketing methods. We do not spend money on paid advertisements and the methods can be adapted to other types of sites. I operate over 100 sites and many use this method and we well into six figures a year combined with all the sites so the method has the ability to produce enough traffic to produce a full time income but this is one of our smaller sites that I do not spend much time on.
Please let me know if you have any questions.
