Perfect vehicle
by Jeff on 1/19/2026 3:26:28 PM
We purchased a GLE 350 before and we liked the design and practicality. Decided to upgread to GLS 580 last year to get more space and more power. We are amazed with the performace. This vehicle gives you space, luxery, and handles very well. - 5.0
GLS580 with Rentech ECU upgrade
by Proud GLS580 owner on 5/30/2022 1:17:49 PM
We were looking for a GL550 and stumbled across the GLS580 series and couldn't get away from it. Hard to find for a good price and I have not seen one on the road. We tow dirt bikes and RZRs so needed something that would tow. Rentech Mercedes approved dealer install took it to AMG HP 598hp and 705 lbs torque. It is an unbelievable family SUV now with that added power. Plenty has already been said here about the plushness of the vehicle. Tires only last 10k miles due to performance demand and I have had a couple of electronic issues that the dealer is working out for me. I am amazed with this vehicle and if the X7 is better I am having a hard time understanding how other than preference on which emblem is on the vehicle. - 4.0

by kishoure on 12/8/2021 1:11:56 PM
this is a nice car, better than the lincoln navigator but no x7 or escalade. this is actually very nice but it misses the well factor rivals have. this is the first time mercedees hass redisigned the gls for the 2020 model year.
