Going From A Cobra To A Gt40

[Dandy Don]

I just sold ERA#593 (Turk's old car) to a Japanese fellow from Las Vegas who is shipping it to a client in Japan. Undoubtedly, this guy resells them for a lot of yen in Japan. He buys only ERAs and has purchased 15 to date.
I was sorry to see the car leave the country----but the Cobra market is pretty soft, especially this time of year. And the buyer's money was as good as the next guy's (who may never come).
After enjoying the Cobra, I'm looking into a GT40. I love the ERA but most folks tell me I would be hard pressed to finish a quality build for under $125-135K.
Several folks have recommended the SPF which is going up in price from $69K to $79K on January 1,2007. I guess I need to sh-t or get off the pot pretty quick. I won't pay an additional $10K.
Any personal experiences on the driveability of GT40s on the street?
Are they claustrophobic with the fixed side windows? Does the Lexan scratch like mad? I assume rearward vision is bad.
I'm 6 ft 2 in. and 235lbs---will I fit (even with a Gurney bubble)?
I plan to visit Dynamic Motorsports between Christmas and New Years.
A $25K deposit is required----
