I kept my 1994 LS400 ( JDM Toyota Celsior) for just under 16 years and had it not been for the opportunity to purchase a newer model I would probably still have it now.
During my ownership I did all the usual fails like the climate control LCD, starter motor and the steering tilt repair, carried out all my own servicing and kept on top of regularly washing and waxing including under washing once a year and wheel arch clean outs.
In all that time it had 2 daft MOT fails, one for corroded rear brake pipes and never an advisory.
Since parting with it the car has changed owners at least twice and is now I believe Sorn with an expired MOT.
If I had the garage space and money to keep both cars I would have done because I know I would never find another in the same condition for reasonable cost.
