With all due respect sir, its not really the job of this board to convince you to keep or sell this car, or watch you have some sort of existential crisis over the level of engineering.
All of us would love to help you replace the head-gasket, chain-box or wiring harness, but the bellyaching is no fun...take it to the OD, before this turns into a troll-flame-war.
I know this sounds harsh, but I hate sequels....anybody remember lynn?
