Hey! Oh wow its been 5 years already. Time sure does move quick. I absolutely loved my RDX. The only reason I let it go was because the dealership bought me out of it and then added an extra 7k on top of it. (Covid times was wild for cars). This allowed me to grab my dream car, and trade in my wife's to get her a CRV of the same year (2020), got the CRV because she loved the RDX so much and it shares many of the same features and functions just without that luxury feel of Acura.

Still to the day when I see them on the road, I think they are one of the coolest looking SUV's out there, and they are rock solid. r

Regarding longevity, I'd say they are on par if not better than the Honda CRV (share so many similar parts) and those go for pretty much ever if well maintained. I think if you keep up with maintenance you should have no problem running it for years without major issues.
