Looking at possibly getting my Mom a new car. The '99 Grand Prix has seen better days and is getting crispy. 191k on the faithful 3.8 Series II and 4T60-E (that probably never had a tranny fluid exchange). Thinking of looking at something like this for her. I personally think it's a real sharp car and looks like it's clean (from the pics). Thinking of taking a ride over to look at it today. http://buffalo.craigslist.org/ctd/4586866120.html I know the Northstars are peppy motors, but are they reliable? Or is it a typical case of preventative maintenance to keep it happy? Thanks.
