This person wants a Volt , fine that is his business. But using his mileage depreciation as a factor is strange. What does he think is going to happen to the vehicle he gets , same thing of course.
Now if it was me I would find the least expensive new vehicle with full warranty that was suitable .
As someone who routinely puts 250-400k miles on a car before washing my hands of it, I would say keep the Acura and drive it to the bitter end.
You refer to “crazy mileage” being racked up, I don’t see the work commute and random mileage as being high at all. What are we talking: 15k miles a year? That’s nothing. I used to rack up 40k miles a year just on a work commute alone…
Using fuzzy math I have 12960 miles a year just for work commuting . Most leases I see are for 12000 to 15000 miles a year. OP has 62000 on a 2015 , must have been a good sized mileage penalty at the lease end.
