Skoorb...what are the numbers you're talking about? I'm assuming you're making this decision purely on a financial basis. If so:
Cost of Prius for 3 years, 10K a year:
$7164 = $199 a month x 36 months
$1909 = (30K miles/55mpg) x $3.50
$1700 = sales tax and fees
$10,773 = Total
Cost of Maxima for 3 years, 10K a year:
$5250 = (30K / 20mpg) x $3.50
$5,250 = Total
So you would have to incur over $5.5K in maintenance, repairs, and depreciation on the Maxima for this to break even. I didn't even include insurance which would likely go in the favor of the Maxima even more.
So in the end you'd most likely be spending thousands more over the next 3 years for a car that drives worse than your current car.
Am I missing something?
Yep, you forgot depreciation of Max and also the maint/repairs, primarily. Here is what I got:
*BASED ON 12K/YEAR LEASE* for 3 years
Prius:
$1950 up front (this covers taxes and all the rubbish doc fees, etc. and one payment)
+ 6615 (35* 189)
+ $2212 in gas (48 city/51 highway and it takes 87 grade)
+ $360 insurance premium
= 11137 total cost ownership
Maxima:
$2000 repairs, cost of tires being more (this is a crapshoot, though, it could be more/could be less)
+1800 in depreciation selling then vs selling now (guess)
+5154 in gas
= 8954 total cost ownership
That difference of $2100 shrinks to about $1100 if I pay $25/month more to get 18k miles/year and start using it in place of our minivan.
I did these calcs on $2.95 87 grade gas, which is what we have now.
I have to emphasize there is nothing exciting about this car. If I'm under any fever it's not new car fever so much as boring old family man fever. Above all else in life I like financial predictability and this gives it to me for a very small premium and reduces all risk of major repairs or highway breakdowns. Those are not really possible to put a cost on. Costs alone the math is in favor of the Maxima I would say, overall.
