Concur, I think at 41, you need to have more in retirement, unless you got a great pension plan.
So at 40 and with $135k salary, you should have at least 2 times that in retirement savings.
Not sure why you have $300k in cash, doesn’t seem like a good allocation in capital.

But it you want to be conservative and have $50k on hand for emergencies, that leaves $30k out of the original $300k.

Not sure how much savings you net/year, but you probably have enough to buy the car, especially if you keep it for a long time.
Of course, if you have kids or decide to buy a house, then you probably don’t have enough.
