I am currently thinking about purchasing an 2002 Audi A4 Quattro with 89,000 miles for 8,650..... is that a good price and will the maintenance and insurance be high?

 

If is the V6 make sure the previous owner did the timing belt, if not you'll end up dumping around 1500 USD to do it. I didn't know and I got mine with 80K on the odometer, but so far is the best car I ever had. $8650 is pretty cheap IMO, but at the same time I'm a new owner myself, I paid 13K for mine and is only an '04.

 

1.8 would need a timing belt too.
