Well, first off, alloy CSX cars are 40k more, not 20k more ($96,500 last I checked). By the time you are done building the car with a 427 side oiler and all, you've got well over $125k or more into the car. However, alloy cars that are well built, also bring good resale, usually in the $125k range, with some as high as $140k. Glass cars nicely built are bringing in the 80-95k range, which is just about the difference in price between the rollers. So the "completed" resale value over cost is about the same for both cars.

As for other differences, even though I like my glass CSX, there's nothing wrong with an alloy car. The aluminum is thicker that originals, and much less prone to damage. Alloy cars are easier to fix, because you don't have to replace a section if damaged like with a glass car (provided you know a good alloy bodyman). The bodies/chassis on the current alloy CSXs are sourced from Kirkham, and there are hundreds of Kirkham owners that will attest to no problems at all having an alloy body.

Hope this helps.
