Hi Reddit!

I'm at a crossroads.  Currently I drive a 2006 car with 93k miles that has a trade-in value of $15,000 (appraised yesterday).  There's at least $2,500 worth of immediate repairs needed to get my car to at least 100k miles.  After that, my research tells me that it's very risky to keep this particular car for much more than 100k miles due to common issues with the powertrain (transmission, engine-which already has a leak, turbo) all of which would be very costly to replace.  Additionally, my research tells me that this car pretty much depreciates to <$5,000 after 100k miles and will likely depreciate to essentially zero (unsellable - would need to part out) after 115k miles.  I still owe ~$7,000 on the loan for this car and make monthly payments of about $450.  This will be paid off in <1.5 years.

For the past two months I've been debating about trading it in for a brand new $34,000 car.  After the trade-in and paying off the previous loan I would financed the new vehicle with a monthly payment of ~ $450 (same as my current payment) but for a term of 60 months.

My question is (and this probably comes down to personal opinion/ willingness to take a risk), is it smart to get rid of the potentially costly, unreliable money pit for a brand new reliable money pit and essentially push out the term of my loan for 3.5 more years OR should I keep my current car, pay it off as soon as possible, and then put the $450 a month I would be paying on the new loan into a savings account for if/when my current car needs the likely major repair?
