you found a 97 prelude for 5,500 ? ok either it has over 160,000 miles on it or its salvage title, preludes the 5th gen models like your looking at dont come that cheap.if you raced them stock the prelude would it has more hp, the prelude is fwd and the 240sx has rwd, the 240sx has better handling since its rwd. both cars have tons of potential for the prelude you can go turbo and have a h22 turbo beast, with the 240sx you can get a turbo or do a swap with a sr20, rbd26 and have a rwd monster
