Know Your Car Willard A Allen 1960 Motor Hi Performance Tuning Guide 1973 Book Know Your Car Willard A Allen 1960 American Technical Society Book Manual has some marks and blemishes on the cover. The spine is tight. The pages have some yellowing from age. There are some smudges on a few pages from dirty fingerprints possibly. Which is typical of a quality book that you put to use! Motor Hi Performance Tuning Guide 1973 is in fair to good condition. There are creases on the cover and writing in the first couple of pages. The staples are holding the spine together. I did not see any rips or severe damage to the book and it is very usable and a nice addition to any collection. No missing pages. Please see all the pictures for the overall condition of both books.
