Wouldn\u2019t recommend unless you like spending your time on the side of the road or at the dealer. Mine just went back to my local dealer today for its 4th alternator in 32k total miles, 3rd one in the last 6 months. Literally just got the car back 5 days ago for the same issue.

Pros: Fun to drive

Cons: unreliable, frequent alternator issues

Vehicle: Audi

Mileage: 51500 km

Reman alternator quality is in the toilet. Not uncommon to have to warranty an alternator once or twice.

Cons: alternator quality is bad
