Towing a Car Trailer

Ok, I'm giving up on the idea of towing with my Lexus. I'm starting a search for a trk. This is not going to make the wifey very happy. I googled towing with my Lexus. It weighs 3950 with a gross weight of 4500 lbs. towing capacity. I may just decide to borrow as many friends have offered to lend their truck. Just hate doing this. It's not an issue I need to address before next spring so I'll keep my eyes open. I checked used trucks and the dodges seem overpriced compared to Ford and Chevy for same capacity. Thanks for everyone's thoughts and suggestions. They have been greatly appreciated.
