Hi - I have a 1999 Landrover Discovery with 180,310 miles, which my husband and I absolutely love. Engine type 4.0L V8 OHV (MFI). Needs repairs to pass inspection, and the quote I received from the Landrover dealer (!) was too much for me -- the head gaskets are leaking oil onto the oxygen sensors (?), so my check engine light is on and I can't get it through the inspection. And we have a slow coolant leak. I don't know what to do, so I was wondering if anyone here has advice about repairing vs. selling at this point. Is it really time to offload the car?
