In my area for that kind of fuel costs, you'd have to be driving about 35k miles a year (for RDX at ~24mpg and gas at $3.50/gallon). Is that across 2 vehicles or 1? I'll be honest, when my Teslas are out of warranty, I am selling them. So if you are putting that kind of miles on a Y, to eat up the difference in fuel vs electricity on one car, that would I could put about 122k miles on the RDX.
Based on my past experience with most Japanese cars, given my usage patterns, I am betting the RDX will be in better shape than a Y would be if I drove both the same way at 120k+ miles. I am pretty certain I'd have less issues out of warranty with the Acura than Tesla. Given the absolutely horrid customer service with Tesla, all the defects I had with my S/3 when delivered, I will definitely be looking for other options when time to replace these cars. The lack of things like ventilated or cooled seats at almost 70k is just a huge oversight on the 3/Y.
If I were to come back net new into the market, I think I'd really look at PoleStar and Hyundai. I like Rivian but I still have concerns about the long-term viability of the company. Maybe unfounded but if I dropping 70-100k on something, I want to be pretty sure they'll be around in the future. All the recent layoffs have me concerned. Hell if the BMW didn't have such an ugly grill and a lot more weight than it should I'd be really interested. I drove one of the I4's and they actually drive pretty nicely. Based on past experience, I know they'll take care of me if I have issues.
I appreciate how much Tesla has moved the EV market but I think they really need to adjust their focus a bit. Sort of reminds me years of ago it was hard to go wrong with IBM in tech and then suddenly it wasn't.
