Which CRM are you using, specifically?
The last couple of CRM we used here (Autobase and now VIN Solutions) have had a "Want List" or "Wish List" function attached to a customer, where we can designate make, model, year, price, etc.
The VIN Solutions "Wish List" function lets us specify to have the salesperson and/or manager notified whenever a match is found. I would not be surprised if most of the others you'll come across have a similar function.
As for "point and click" emails, are you referring to being able to knock out an email with a template and not type each one out, send out certain followup emails automatically or just blast a list of customers with a specific email? All three of those are pretty common among the few CRM tools I've observed, so depending on which CRM you have you might already have those functions.
As far as tracking which internet leads result in sales, that one's a two-fold battle. For one thing, you've got have salespeople in your CRM not creating duplicate records and distributing your customer history across several leads/customers. If they don't follow a constant practice, your data will lose integrity over time and tracking becomes a tangled mess instead of a tidy web of customer history. Got to do it right the first time every time or it's eventually useless as a measuring tool.
The second portion is just staying up to speed. If you're expected to be able to keep on top of this data -particularly if your pay is tied to it- then you should have access to your CRM "high enough" to let you check in on customers you've set to be in, regardless of whether they are in your name or not. Even with the best equipment and systems, there's still going to need to be that due diligence to keep tabs on every customer you can - a good tool just helps to make that part easier and less time consuming.
If your CRM supports none of this, I suggest getting very comfortable with spreadsheets and making your own tidy trail of data to follow. I'm still in possession of our year-over-year trending data and lead distribution curves from when our former CRM did not support these functions, for that very reason.
Hopefully some of that answers your questions.
