Where can I find reliable user reviews for used road rollers?

Last week my cousin asked me to help him find reliable user reviews for used road rollers because he wants one for small road repair jobs. Honestly I thought checking reviews online would make things easier but after few hours my brain started hurting. Some websites gave almost every roller five stars which honestly felt fake after reading for little time. Other places had workers fighting in comments about vibration problems engine repairs and expensive maintanence costs. One review said a roller worked perfectly for years while another person complained the same model broke down after few months. The reviews was all mixed up and my cousin kept asking which people were actually telling the truth. After some time I stopped trusting half the things I was reading online.

Next morning we visited a heavy equipment yard outside the city and talked to few operators there. One older driver explained things in a much easier way and honestly it helped alot. He said the most reliable reviews usually come from contractors and machine operators who use rollers daily on real projects not from seller advertisements. He told us to check contractor forums machine videos and long term owner reviews where people share fuel use repairs and real work performance honestly. One roller there looked shiny from outside but during startup it made a rough rattling sound and the seller looked nervus trying to ignore it. My cousin quietly laughed later and said online photos and perfect ratings can hide many expensive problems.

Later that night we searched more contractor discussions and machine reviews on alibaba and saw workers arguing nonstop about which used road rollers are actually reliable. Some people cared more about low prices while others only focused on maintanence and spare part costs. Now I keep wondering if there is really any perfect place for honest roller reviews or if every buyer just learns from mistakes after buying?
