My old 04 Volvo Xc90 had 311k on the dash before the alternator gave up lol. Doing better than that!
Pros: high mileage
Vehicle:
Volvo XC90
Mileage: 500499 km
Denso alternators are the best. Denso makes great products. I do a lot of side work on Hondas and I am so thankful Denso offers their stuff outside of the dealership. I replace alternators, a/c compressors, oxygen sensors, etc all the time and I choose Denso bc it's basically the same exact part you receive in a Honda box but for half the price.
Pros: best alternators, great products
Vehicle:
Honda
At 48K miles I experienced an alternator fail (car was running great at the time).
Vehicle:

Mileage: 48000 km
Get the Bosch, including the warranty from them, and be done.
I replaced mine with a Nissan Quest alternator works pretty well and is cheaper with a higher current output there is a write up in the forums for it
Pros: higher current output, cheaper
Bosch has a support site that shows what alternators they recommend for your VIN number. AL20X (65A) and AL172X (65A) are the two Bosch shows. However most of us know the original was a 90A unit AL30X.
Pros: Bosch support available
Cons: original was 90A
Vehicle:
Volkswagen Jetta
Part number: AL20X, AL172X, AL30X
B5/5.5 alternators come from two vendors, Bosch and Valeo. I've heard they're not interchangeable because of different pulleys.
Cons: not interchangeable
Vehicle:
Volkswagen Passat B5
So I go to get some iced coffee because Dunkin just came out with pumpkin and the car doesn't start. Sputters. So I call roadside assistance for a jump. They tell me it can't be jumped and it's probably my starter. Real kicker is I then call for a tow, tow guy shows up and jumps it???? So I HESITANTLY drive it to the dealer who determines it's a bad alternator.
Cons: car doesn't start, sputters
Vehicle:
Nissan
It's a dice roll. I've had some success with them, but when I put a reman one in my Focus, it only lasted 2 weeks.
Cons: only lasted 2 weeks
Vehicle:
Ford Focus
