This meets all the qualifications and while not as pretty as say a modern Porsche, it does have a certain "I don't know what". Light. Fast. Economical. Efficient. Fun.
Sure it might be a bit old, and its heavy modifications don't exactly scream "I'll start every day, I promise". But, I just saw one of these at Fuel last saturday and it was f'n sweet.
Toyota FT-86. I have no idea what the final specs on this car will be but supposedly it will spec out at 26K in premium trim. Depending on the engine available, this could be a real nice ride, especially with some engine work.
