Everything you say makes perfect sense - good thinking. Thanks for asking for my perspective.
Three mitigating factors in your case:
- Money borrowed under a home loan is cheaper than a car loan. Using the Tesla calculator I shared, I'm guessing your trade-in is worth about $14,000? A 2% lower loan rate will save you almost $7,000 over 8 years. I agree that's a better way to borrow the money.
- More significantly, as you note, your current car costs you ~$620 / month. If you're willing to forego the 407 (HOV lanes towards your home?), given the premium on insurance, electricity, etc, you'd "save" ~$500 / month switching to a Tesla. So your $900 payment is net $400 / month / 8 years.
- The added detail about having a net worth over $600 K and being employed in IT supports you having more cushion to leverage than some others.
Staying with car loan scenario, personally I would increase the payments (and eat out less) but shorten the period, say to 6 years. My calculator estimates your loan would cost $1,175 / month (see below) but after that, the same payment could go into TFSA or RRSP for your long-term benefit. This assumes you keep a car for more than the few years (financially-wasteful) people do who get leases (worst investment evah!).
If you bundle the loan into your mortgage, you save ~$7,000 but the payback duration gets averaged out. You might need to renew your mortgage for many extra years, but at least that loan is mostly towards building your equity, and at the lower rate.
Of course it depends what's more of a priority for you - there's no way getting a Tesla will "pay" you back financially. But, here's an idea (and I said the same thing when my son and daughter-in-law were anxious about buying their first-house):
- Buy the Tesla and see how the payments work out for one year.
- Use the mortgage rate, but aim to keep the duration as short as possible - a benefit of a mortgage is that the monthly payment stays the same even as your salary should go up year over year, so year 1 is the toughest year of paying off a mortgage.
- If the costs are too much, you sell your Tesla after a year, and even if it's only worth 70% of what you paid, that's still double or quadruple what you'd need for a replacement vehicle (a used car - suck it up, Princess). You take the extra 1/3 or 2/3 from the Tesla sale and make a bulk payment back into your mortgage to reduce its monthly payments (make sure your bank let's you do this).
- Your risk is not completely $80,000 over 8 years. It's 1-year's depreciation, say ~$15 K worst case.
- There's a chance the feds will introduce a rebate that lowers the resale value of the car. That would suck if you buy now. You can't control that. I try not to worry about what I can't control. Don't expect and you're never disappointed, is my philosophy. The rebate's unlikely to be $14,000 though so I doubt it'll be as severe as others are fearing.
- In other words, in a way the risk is not 8 years of high payments, it's paying ~$15,000 for one year of driving a Tesla and finding out if it's worth the impact to your lifestyle. That and your escape plan involves downgrading to a 2nd-hand car. As an "experience" there are worse bets. In my son's case, the maximum penalty to try out paying for a home was the move cost and the realtor's fee (assuming a stable housing market), but it wasn't "OMG I am stuck for 25 years!!" Buying a Tesla has less financial risk than buying a house, but both the depreciation - and the fun! - is more.
Is this helpful?
PS Out of the dozen cars I've owned, only 2 were new: a Pontiac Firefly (3-cylinder Suzuki!) which I bought when I was a courier and could therefore write-off the purchase, and my current 2013 Suzuki SX4 winter car, which I bought when Suzuki left North America and was on sale 25% off (new in 2013 for $17,500). The sweet spot are cars 2-years old - you can detail it for $150 to make it look new, but it costs ~$40% less than new.
