I picked up for 50p acopy of "Car Mechanics" dated April 1967.

120+ pages of fascinating stuff that took me back to my youth.

One thing I didn't know, it said that GM, Ford and Chrysler were offering 5 year/50,000 mile warranties on their cars in the USA provided they were serviced every 6,000 miles. Did that apply from 1967 to present day?

Lots of articles on engine tuning, ads for all kinds of parts and accessories.

A guide to used cars lists top speed, mpg,replacement cost of engines, (typically £50 to 70 for UK cars, but £540 for Mercedes!), gearboxes, tyres, brake parts etc.

I used to buy the magazine regularly in those days, running old cars it was often helpful.

Present day equivalent I suppose is "Practical Classics" and the valuable resource of this forum's technical section.
