If you really want to buy a Kirkham and need to work one more year to make it happen, then do it. Those are terrific cars.
I chose to retire at age 56, in March 2015, after I reached my minimum service time and minimum retirement age for a full pension and lifetime health insurance coverage. These past 3+ years have been the most enjoyable of my entire adult life. I certainly don't miss the hustle and bustle and emotional stress as a nuclear engineer. It used to beat me down, and it sucked the life out of me for 30 years. My home mortgage will be paid off in 3 months. I'll be free at last.
