You can get a good idea of bottomline ballpark pricing with
www.carsdirect.com but those prices are beatable. Incentives play a role as well; there's often cash alternatives (dealer or consumer rebate) if one doesn't take a low APR or lease factor. Excellent finance rates are available at
www.capitaloneautofinance.com if you don't have a good source already. On another thread here I saw someone mention SAAB 9-2Xs could be had for around $8K below invoice...
Sounds like you plan on keeping the car a long time, right Cliff?
