I'd lean towards the 56. It's just too cool for words. Or the 55. You gotta love the first gens. Or the 57, the fins and bumper are just sleeker than snot. Oh geeze man, just go get one already!!!
Where in TX are you? There's a good TX following here. I own a 56 and hope to have it on the road by spring time. This is a great site full of great guys/gals. Enjoy your stay!
