Car Dealers do not need a portal. A portal is more like www.yahoo.com, workformodels.com, www.google.com, etc. 

Please before contacting us for portal development realize a portal starts at 10,000 and works its way up. I personally have never spent less than 10,000 on a domain portal name site over a period of time. There is no completed cost to a portal. They are living breathing growing machines. They require constant mainenance and top notch programmers. The key word seo has to be Excellent! If you think you want a portal sharpen your pen. Sharpen your thoughts and realize the expense before hand! We build them, We maintain them and we have years of experience at making millions on the WEB! However, we do not bid every job we see. We only bid jobs we believe will succeed. We bid jobs that are realistically thought out.
