I have a similar difficult decision to make. My LS400 from 1995 has now done 142,000. Every now and then it needs large sums of money being spent to keep it running. The latest is a new steering rack - over £2000. Much as I hate to see this beautifully comfortable, smooth running car leave me forever I find it very difficult to justify spending more than the car is worth to keep it going. I guess it is different if you are prepared to work on the car yourself but I am more than four times as old as the car and not willing to play that game any more. So sad as it may be I think it is probably time to move on.
