I see some here really know their VW Beetles!..I had four in my youth,a '63 was my very first car,and my uncle sold me his '63 VW "Khombi" Transporter that had jalousie crank out windows and a factory paneled camper interior--probably the coolest thing I ever had (and didn't realize it at the time!)..
I also had a 1959 Beetle,and a 1953 Beetle with spilt rear windows when I was 12,my brother bought it for a parts car and used the engine,I used to play in it!..I wish I still had that now,it would be worth a fortune,thing was in very nice shape then,no rust..
I'm not that familiar with the 1967 and newer VW's,but they are similar..I'd say its well worth 500 if its not rotted to death,in fact,you'll be lucky to get it that cheap if it isn't rotted,because they are geeting very hard to find now..I had a blast in my VW's,especially the "Hippie Bus",and I learned a lot about cars and engines fixing them up..That one to me looks like a '68 or '69 with some other years lights added,as suggested already..Super Beetles also had a louver behind the rear quarter windows and a larger windsheild ,in addition to Mcphearson struts up front..I think 1970 was the first Super Beetle year..
I highly reccomend the book I had,I think it was titled "The Complete Idiots Guide To VW Repair" by Henry Muir,I lent it out and never saw it again,but a local library will have it most likely..a great read,and very informative and descriptive..another good one is "Small Wonder",a book about the VW history from day one when Ferdinand Porche made the first prototypes with a radial engine!..
Ahh,yes,I can smell the interior from here too!..many memories came flooding back when my older brother bought a '60 Beetle about 5 years ago,and I stuck my head inside it..I was tempted to buy it when he sold it ,but like him,I found I no longer FIT too well in it,even though I was just as tall when I was 18 as I am now!..guess I got bigger all over too!..he got 6K for it and only paid 600 I think,but he did the whole interior over and invested a lot into the engine and other mechanics..body was soild though and didn't need hardly any work..
Hope you find its worth buying and you end up with it..VW's are a cool car and more rugged than an anvil..I beat mine mercilessly ,I had those wheel adapters to put GM rims on mine,and used L78-15 stuuded snow tires on it in the rear,there were sand dunes in pits nearby I could climb with it that many CJ Jeeps only got halfway to three quarters up,and I won a lot of gas money betting them I could reach the top with my Beetle!..
I always took the back roads home during snow storms too,and looked for unplowed roads,it was like a 40 HP tobaggan,it rarely ever got stuck!..only thing I hated about my VW's was NO HEAT!..I used a sleeping bag for seat covers in the winter!..mine got about 30 mpg,with the 40 HP motor,the Bus only got 15-22 though,it had a 1500cc 53 HP motor,even though it was a '63.it came factory with it in a Bus that year..I miss all of them now!..
