Any car I own would look showroom new inside and out after 7 years lol. It all depends on how you care for it. A poorly cared for LX wont look showroom new after 7 years. Lexus high end cars do age well but its not magic.

In fact I am continually amazed by how well the interior of the Pacifica cleans up after it is absolutely hammered inside constantly.

 

All three of my GSs have been completely rattle free, though admittedly two out of three were low mileage.

The Tundra has a driver's door rattle I need to tackle, though I've removed the door panel several times for modding, so I may have caused it.

Now the Highlander...arg. It's my wife's daily. I drove it the other day. I could not figure out if it is plagued with major rattles or it is the 9,301 water bottles rattling around, the toys rolling around the floor, or the goldfish crackers sliding in the seat tracks. That poor thing needs a detail day...
