You describe a litany of 'problems' which almost certainly would have been revealed by a competent
used-car pre-purchase inspection and now you complain that you bought a "lemon"?
Write it off as an (albeit perhaps expensive) lesson learned and
- Get it thoroughly inspected by a competent mechanic to identify all issues and prepare an itemized estimate to fix each issue
- Make the difficult decision to either have some or all of it fixed OR resell and take your lumps
Buying a used car requires due diligence no matter who is selling it. IMO relying on "Carfax" or similar is never
a substitute for competent and thorough inspection at the time of purchase**
. If you are not competent to make that inspection then you must pay an independent party to provide that service. Everything in your post indicates that you failed in that regard when you made your purchase decision.
Sorry if that seems harsh, but reality bites sometimes.
Good luck, take more care next time you buy a used car.
the fine print on any 'car condition report' like Carfax or similar .... you'll find that they only, at best, promise to disclose information available from DMV and similar reporting sources and limit their liability accordingly. If anyone thinks that means those 'reports' guarantee the actual meaningful condition of a car
at time of purchase .... well, shame on you (if you think all vehicle damage or crash gets reported to a DMV or logged in a dealer reporting system, you're dreaming)!
IMO such 'condition reports' can be useful to eliminate
potential candidate vehicles at best
to give assurance to include
a potential candidate vehicle in your final buying decision. IOW, use 'Carfax' to ID vehicles NOT to buy, not vehicles TO buy.
