Gave up my black '08 MB E550 4-matic to my daughter in med school who needed a reliable car last July, leaving me to drive the battle-scared tank, a 2004 Lexus LX470 that has trained 3 kids how to drive in safety. That car has now 170K miles and still has a shine that XPEL would be proud of, except for the Rocky Mountain salt dings on the front end. I ordered the 90D last April knowing that we would be down a car at home, and I had not been a new car owner in over 10 years, so this decision was my turn (wife said "you make the money, you get the prize"...God I love her!). Wife drives a new pearl white GX460, 3 rows of seats. So that's why I ordered 5 seat X. My youngest kid needs 25 more driving hours to get his license, and he will take over the LX470, so he won't drive even with a license until my 90D arrives, or else he'll drive a 96 Jeep Wrangler with stick shift for a while. Yea, we will become a 6 car family for 6 people, but 3 cars will reside in Denver. The rest are scattered amongst my kids in college and grad school. Cant wait till they become self-sufficient. Does that start by age 30 or later?
