I owned a Gen 1 RX-7 for several years because I couldn't afford a 924.
Nice little car, as expected it is very basic. 100HP as I best remember. Fun to drive, just change the oil and filter often.
Also owned a Gen 2. Much better car. 140 HP with some low end torque.
But today, I would go with a Gen 1 because I simply like the way they look.
