These vehicles usually need constant work for two years when you buy one. After you replace all the parts that have worn out after 20 years, you can finally enjoy the vehicle a bit. My SD is currently in this condition...........and it's taken $4K worth of parts.

So, if you're not inclined to spend the time and money to correct all the "issues", I'd suggest that you sell the vehicle. I'm sure you can recover the amount that you currently have into it. From here on.........it's all downhill. None of us can sell the vehicle for the amount of the parts plus the purchase price. If you pay for labor.............you'll drown.
