What is your budget and what are some of the highlights of what you'd like to see; color, air v. water, etc...?
We (Beck) have one used Gen 1 Speedster on consignment here now and have a Gen 2 that will be available int he early Spring. You can view the Gen 1 under the pre-owned section of our website. The Gen 2 will likely not make it to a public posting on our site.
Last I heard, Greg at Vintage had one new build available, but was thinking about keeping it for himself as a demo for a while.
LOTS of scams out there, so just keep in mind that if it sounds too good to be true it may just be.
You came to the right place for opinions and internet sleuths, so don't be afraid to post your findings here as you come across used cars. Likewise, if it is a Beck you can e-mail me with the chassis number and I can pull the file and verify the car.
