I was just searching the lexus forum to find out what type of problems their GS400 series comes up with. and I was a little jealous to see that all their forum postings were mostly about upgrades, new kits, wheels, speed etc. And I had to think about our W124 forum in comparison. Almost all the posts are mostly about troubleshooting and rarely any happy posts trying to 'upgrade' their car rather than trying to 'fix' what's broken...
