In need of advice from Lexus lovers. I find myself having to choose between a 1995 GS 300 with 189,000 miles or a 1995 LS 400 with 129,000 miles. Both have been well maintained since purchase with regular schedule maintance visits. The only major problems encountered with the GS include replacement of the distributor O ring, power steering pump and rack assembly, sensors, water pump, damper sub assembly and the rear main seal. I assume these can all be expected as normal wear while enroute to high mileage. On the other hand, the LS has had no major repairs. As the LS gains mileage can I expect to replace virturally the same items. or do they have a more reliable history? I rarely see GS's of this model on the roadways and so wonder if they are considered somewhat collectable? Any suggestions from folks who know these cars best? As you can see, I am literally riddled with indecision. Thank you.
