2000 Audi A4 Quattro Reviews
OEM Brake pads create a ton of black dust. Aftermarket pads are far better in all respects.
Body has held up very well for 120k, still very solid - no rattles.
Exhaust system went at 110k. Price to replace pipes and muffler was nothing short of outrageous $1000-1500 no matter where I shopped. Purchased APR stainless performance exhaust for $950 and had it installed at local muffler shop for $100. Sounds slightly (5-10%) louder, but my wife thinks its just fine.
A/C is not the most powerful, especially when idling.
