2006 Lincoln Town Car to replace 2003 Cadillac Seville STS

I would think that Cadillac would take such pride in their high-end cars they would not tolerate an 11yr old car having an oil leak. They should be so ashamed they would fix it for free! Our 2001 Honda Odyssey is still going strong after 160K miles. My car before that, a DeVille and before that an Eldorado, also had lots of maintenance problems. Maybe Cadillac could take some lessons from Honda??
