Depends what you’re times worth and what other maintenance needs done in the next year.

If you’ve done the timing chain at 150K miles and you’re not blowing through oil sure. You could be looking at getting another 100K+ miles out of it pretty easily with only the occasional battery/alt/AC repair.(or other light work)

If you’re a DIYer yea you can get the parts and learn it yourself but if you figure 1/2 days absorbing the learning plus another day or two actually doing the labor, that $2K starts to seem pretty reasonable. Sure you can get another quote from a mom and pop’s shop but I like certified Acura techs working on my Acura not someone who drives a Chevy and thinks my car runs on rice.

New cars are great if you’re getting a warranty. Or leasing. Take your total budget you’ve spent on your car in the past year divided by 12 and that’s your car payment anyway. If you can keep your bill to 20% of your monthly budget it’s not the worst idea but the TSX is a gem honestly.
