- advertise in automotive-related magazines and forums
- advertise on social media
- advertise in ezines
- advertise in specialty directories
- buy ads on networks like BSA...
I wish I knew of free ways to get leads, but I don't think there is one (other than knowing a friend of a friend of a friend that has a lead gen biz and is willing to offer you a free trial or something...)
Also, I don't know the state of ezines anymore, but if you manage to find quality ezines they can be extremely rewarding. About 15-16 years ago I purchased an ad in a MLM ezine (I think it cost me $250 if memory serves me well) for 60 guaranteed clicks (it was a very good ezine at that time, that's why it was so expensive) and I got over 300 clicks and 41 leads from this campaign. Unfortunately, at that time I was being newbie and was throwing money left and right without knowing how MLM works or how to get the most out of my advertising, so I got these leads into scammy deals which got me nowhere lol
But anyway, ezine advertising - if still existent - works like a charm. You just have to find quality ones from people you trust. Back then, DoE was one of the best ezine databases online, I paid over $300 to get access to it, but it seems dead now...
If you can't find ezines, I think buying ads is the next best thing... also advertising in magazines and forums can yield good results, but it's probably expensive and / or takes a long time. But hey, you gotta compromise somewhere
