This is a 2003 DHS with 90K. Coolant light came on and I was advise it was a head gasket along with an oil pan gasket that need replaced. Quote was 4K. Can I get this repair cheaper or is it time to get rid of this car. I like it and would like to repair it if I thought that would do it for another 90k other than normall maint. Please advise and thanks!!
