1995 Audi 90 Quattro Sport- Upgrades?
 

Alright guys so bear with me here. I'm brand new to this site and only just getting into cars. I have a 1995 Audi 90 that I absolutely love. I'm wondering what I can do to upgrade it? What parts work? What does everyone recommend? I'm open to lots of ideas so it would be so handy if you could help me out! Thanks y'all.
