I understand what you're saying, no worries. Like I said, the one "plus" to leasing is that it allows you to drive a more expensive car for the same money than if you purchased it. Not saying or implying that you're hapless rubes (love the term by the way), but by it's nature, a lease takes advantage of consumers. And again, there are plenty of people who don't mind spending a little extra so they can have a nicer car. That's a personal decision. Heck, I spend some of my disposable income on things that would make others shake their heads.
The key is what you said..."drive the vehicle I want". That's what leasing may allow you to do. I understand you don't want to drive an older vehicle, but what would you call "older"? Keep in mind that most cars now need nothing more than routine basic maintenance for 100k miles or more. Purchasing instead of leasing may require you to step down one price level. For example, instead of a $24,000 Nissan Juke lease, buy a $17,000 Nissan Versa Note (the Note and Juke are very closely related). Put $2000 down and $300/month on a 5 year loan...just roughly speaking. That's about the same as you'd do with the lease. Drive the car for 4 years. Now you're ready for a new car. Trade the Note in. You may still owe $3000 on the loan, but the car is worth $5000 on trade. So you've got $2000 equity in your pocket. If you sold the car privately instead, maybe you get $6500 for it and now you've got $3500 in your pocket, instead of nothing if you lease. Plus, none of the multiple fees that leases tack on, which can add up to a few grand.
Alternatively, you could go buy a low mileage 2015 Juke instead of a 2018. The Juke hasn't changed much in years, so a '15 is identical to the '18, but will cost 40% less.
Some people like driving brand new cars all the time and switching them every few years. If you don't mind all the strings and financial downsides that come with a lease, then it makes sense. As much time as I spend in a car every week, about 15 hours a week, I want as nice of a car as I can. So I understand the temptation.
