Yeah, if you expect astronomical miles then the math looks different! But...i got $76k to budget for repairs to be over that.
A) Do you expect to pay the same amount for repairs during the last 90k as you did in the first 90k? Even without the ELW?
B) It sounds like you've received far more than $6k worth of repair work in the first 90k. Perhaps I've misread.
C) $76k sounds like a lot. Enough to buy another brand new van if things get tough around 180k I suppose that if you put those miles on fast then you aren't going to pay nearly as much in insurance/mile as I'm calculating (expecting only 20k miles per year). What about trolls, parking, speeding tickets, car wash, city stickers, etc?
D) I was probably too pessimistic and hasty with my calculations for the $0.59/mile deduction. I have a few expenses, that many probably don't, which easily push me over that number. That said, if you plan to drive the vehicle till 120k miles and then sell it for $10k, and you expect to pay for full coverage commercial insurance, buy the premium fuel and get all your service done at the dealer, it's not too far from $0.59/mi without any repair costs.
