Buy??? Grand Vitara 3.2 “20 years”

Hello together, I seriously play with the idea to buy a Suzuki Grand Vitara 3.2 “20 years”. EZ: from 2009 -Automatics -Complete equipment – up to max. 100t km Does any of you have experiences with the vehicle, especially with the engine, over several 10t kilometers? What about the automatic/the transmission? What is blatantly important? MT already contains this one or other topic, but unfortunately only more general and often not based on this engine. In addition, I would like to retrofit an LPG system. Which manufacturer of a gas system would you recommend? Does one of you know a trusted LPG retrofitter for this in NRW (also via PN) ? Many thanks for your considerations and comments… Many regards Dabido PS: I would like to have a six-cylinder petrol tanker and no diesel. Small workshop equipment is available except for direction bench.
