As a PS., every year, whatever, the car, I change the pollen filter, use a stick-it-in-the footwell air-con cleaning aerosol, and check the air-con temperature.
Cost... about £15? Satisfaction... priceless!
I'm not sure anyone knows...
Some say never and others say, yes.
Had mine done back in the day and I did feel it made a difference.
It's probably a similar argument to that of premium fuel?!
If it was me, I'd stare under the bonnet for anything obvious, and then think if I bought it from Lexus and therefore does it have a Lexus warranty, or serviced at Lexus with a Relax warranty, or think about my local and trusted independent garage for a check...
I'm sure others here will share much greater wisdom.
Just an FYI...
A pre-MOT check sounds like a good idea.
Corrosion underneath seemed to be the biggest problem for me ( my car that is! )
Also water getting behind the plastic wheel arch inner covers and causing rust.
Not easily visible but certainly worth being aware of...
Agree.
An interesting thread.
Steering wheel (VISIBLE) locks generally look good.
I have read reviews where some have become locked on...
I guess even one that 'looked' locked on would be better than none at all?
