$60K to spend, but on what???

[COPO]

Ok, 2 door coupe. How about this one, Mercedes Benz CL65:

This isn't about a car; it's about an engine. Forget Vipers, Ferraris, Bentleys, all those rumbling turbodiesel-powered American trucks, and anything else you think has punch. The CL65's handbuilt, twin-turbocharged 6.0-liter V-12 spanks them all, grunting out 738 pound-feet at just 3000 rpm. And that's only because Mercedes-Benz electronically limits it to that number; fully unleashed, it'd be good for a transmission-shredding 885 pound-feet worth. Its 604-horsepower rating almost gets lost in the blur.

AMG's power mongers begin with the architecture of the twin-blown V-12 that powers both Maybach sedans and several upper-deck Mercedes and gives it a significantly longer stroke, upsized pistons, larger fuel injectors, higher intake-valve lift, longer valve-opening duration, larger turbochargers packing 22 psi of boost, a super-large air-to-water intercooler, oil jets that spray the bottom of each piston, and a big oil cooler. This amazing powertrain also can be had in the SL65 AMG roadster. This elegant locomotive's 3.8-second 0-to-60 time toasts that of Viper's and Vette's, all of which average in the low fours. 1/4 mile times are 11.81 sec. @ 120.9 mph

At $180K, I guess it's a little over the budget, but maybe you can find a nice used one.
