The best-kept secret of DrivingEnthusiast.net is that it is actually a network of 5 individual sites:
And that is the problem. Looking over site stats, we see that few people go from one site to the other. The sites were originally split apart because of different audiences: S2000 owners don't want to know about Fords, etc. (and the converse is even more true). And the Car Movie topic needed to stand on it's own. Hence, 5 individual sites. But the owner has interests across multiple topics, as do many readers.
To solve the problem, we've added a blue navigation bar consistently across all 5 sites. This provides an indication of the other sites to readers, as well as consistent navigation.
Navigation around the network is easy. Each of the 5 websites has the blue navigation bar at the top of the site:
Click on the 
logo (mouse not shown) and links for the other 4 sites will drop down. Click on any of those 4 to proceed to that site.
For those of you interested in building your own sites, take this as a lesson learned. You may have multiple interests, but in this hobby some reader's interests often are closed. And site stats need to be carefully analyzed to see if your sites are generating interest in each other.
In the longer term, more sites can now be added. But to keep consistent, from now on we'll add them as subdomains in the form of xxxx.DrivingEnthusiast.net where xxxx is the name of the topic (car) in question. This will save on the cost of domain registration and ISP costs. Remember that the DrivingEnthusiast network is a private non-commercial entity (unlike 99% of the sites on the web for automotive hobbyists). Referral fees earned thru Amazon and Google are used solely to (barely) pay for the ISP and domain registration costs.
