So I have a 1989 Chrysler Conquest TSI. Mint condition, got it from an old lady, its 100% stock.

The shift knob is slightly torn up, and the tape player doesnt work. The only 2 probs with the interior. I cant decide if I should just put a cd player in it and replace the shift knob or leave it exactly how it is. I like that its made it this far without being bastardized, but the lack of good music, and the raggedy-ish shift knob bother me. What does everyone think? Upgrade...or leave it vintage?
