How long will Volkswagen beetle last?

Forever. The Volkswagen Beetle is the most loved car in history, so it's the classic car with the very best parts availability. With very, very few examples, you can get a new example of any part for any Bug and have it shipped to you in a couple of days--or at least a part that WILL work if you make it. The biggest example of a No Longer Available new part is the trunk lid for a Super Beetle. This is because Volkswagen sold the stamping die set to an Italian company, and they broke it. The hardest part to get for one seems to be a tire--VW uses a skinny 165R15 tire that doesn't fit on anything else. You can get them, but it takes some searching. (Pep Boys has them. Tire Rack does not, which is weird because they have everything else.)
