$16,000 is pretty cheap for a N/A current shape Supra, cheapest I've seen them around for these days is $18,000. Pondering one of these as my "next step", or an Altezza...hrm....
Sorry no idea on the weight, but a Supra on these forums with a 2JZ-GE makes 120 odd KW at the rear wheels. In manual form did a 14.68 1/4 mile. That was a MA61, but I'm guessing the 1/4's would be pretty similar.
