1/3 of a FGT?? :lol
Seriously, I recently picked up an used low mile SL55 and it is very fun. Hard top convertible two seater, 493hp, 516tq, lots of fun tech and you can add 55 hp/tq and raise the limit to 200mph with a 4K chip upgrade. Lots of car for the money. It is an automatic, but it has paddles and tiptronic altough I have not used them. May be a little heavy for you but as a less expensive second to the FGT it is :thumbsup:thumbsup
Had a Viper and liked it, but it was a tight cockpit if you are tall. Immense thrust and with that big 10 cylinder out there in front of you is a sight to behold. More pure sports car.
Make sure you post what you decide on. :cheers
