Monkie: Your best bang for the buck right now is a limited time offer from Kirkham on their 427F for $25k. Since you're building it yourself, you can take advantage of Kirkham's desire to put about 25 cars out there being built by people with no manuals, but with factory support via phone or web site. Check it out at
www.kirkhammotorsports.com. The Kirkham's may have a few more seats available. Last I heard they were going fast. That's where my money would be spent at the moment.
Also, Kirkham (even a Kirkham fiberglass car) will maintain a high resale value by nature of their quality record.
Good luck, and I wish I had the cash on hand to jump into the fray. I'm sidelined for now.
