Interesting tax implications, something I never would have though of. (I'm not selling anything, but found it very interesting when doing the math.)You're replacing the CX-5 with another vehicle. If so, investigate how the sales tax would be computed on the car you're buying, depending on whether you trade your car in or not.
Here in Ontario, our tax rate is 13%, so paying tax on the full purchase price vs. paying tax on the difference between the new car price minus the trade in, would be significant.
I bought my car 2 years ago, and traded in my old Altima (for peanuts), so I never checked to see what the tax implication was.
I'll have to dig up my invoice and check.
To the OP: If you only have to pay tax on the difference between the two vehicles, then I'd trade it in for sure.
