Lexus: $15K, 100K miles 99'-02'
Jeep: $15K, 30K miles 03'-04'

Ok, so the Jeep clearly looks like a better bet. However, I feel like...not neccessarily if the Lexus (toyota) can last 200K-250K miles, and the Jeep only lasts a little over 100K miles.

The lexus is my dream car, and I need to know if it would be worth it to get it over the Jeep. Thanks guys!
I'm really not sure on how long Jeeps can really last...

go for the jeep.

Jeep: newer, valid warranty, IMO better looking, and more powerful.
Good Luck.
