A P15 was my first car when I was 16 years old, back in 1964. My grandfather bought it new, it became our family car, and ultimately my car. Learned by necessity, as I couldn't afford to have it professionally repaired. Learned by trial and error to replace a clutch, change a head, replace points, swap engines, repair a leaf spring, etc. Fairly straightforward repairs, but much of it was new to me. It was quite a learning experience, and here I am with another P15 (well, it's not really stock anymore, but a P15 nonetheless). Had this one since 2006, and wouldn't dream of ever selling it.
