i had a 92 civic auto and i did the swap to 5 speed. the car wasn't worth much but i spent about $2300 on the swap. when i took it to the dealership to trade it in for my 97 civic, they were like thanks for not bringing us a gay automatic! and gave me $3000 more than what my car blue booked for. auto to manual doesn't hurt resale value so if you've never sold a car that you've done auto to manual swap, don't say the resale value sucks.
