Had great luck with Legendary. As stated before, let the seat covers sit in the sun for a few hours. If the foam is wrecked under the seat covers, acquire new or better used. Baby powder rubbed over the foam also GREATLY aids the installation process. You do not need specialty tools to disassemble and recover the seats, but you can buy hog ring pliers at harbor freight for $5 and a bag of rings for $2. The hog ring pliers will save you a lot of time and cut effort down to nothing when reattaching the covers.

Buy and do the dash pad yourself.

If new panels are out of your budget, they do make a really nice interior paint system that works decent. Prep is absolutely critical here

If your carpet is only a few years old and the car is rarely driven, pull it and steam clean it, then let it in the sun for a day.

Headliners require patience, if you dont have any, call interior shops for a quote for install.
