I collect many automotive books. 75% are Ford Mustang books but I have many others, Ferrari, VW Bug, Racing, Old Fords.
Just finished reading this wonderful book on the VW Beetle. If you love Bugs this is a must read. Still holds up since it was written in 1965. This is the 1970 edition. Next to it is a a vintage book I got from a co-worker that's knows I'm a car nut. This is the April 1958 second edition. It has been updated to 50 cars, some I have never heard of.....Gregoire, Nardi, Pegaso to name a few.
Far as I know the VW book is still available but the Sports car book can only be bought second hand.
