I know it's been a while since this was active but I thought I would just share this. I only paid $550 for my 2000 GP SE. I hate the fact that it's only a 3.1 but in 2000 they gained a little HP over the pre 2000 models. My engine only has 45,600 miles on it and I have no engine issues, other than loosing a tiny bit of oil. Not sure where its going but I changed the oil at 43,000 miles and here I am 2,600 miles later and I've only about an 8th of a quart of oil. I really like my 3100. I do have transmission issues, but that's not related to the type of engine, lol
