Not a pro just a weekend warrior have 4 vehicles to take care of Gen 1 Raptor (Mine) Gen 2 Raptor (Son`s) Chevy Colorado work truck I drive at work and back and forth from work (so I figure I should maintain the appearance) and my wife`s 04 explorer. No major correction needed just swirls and what not and polishing. Money not really a concern as I want to buy the best the first time. Spent lots of time on various forums but getting more confused the more i read. Was looking at and pretty locked in on a Rupes 21 but think a 15 may be more appropriate also looking at a Flex XC 3401 machine and GG 6 & 15. I have came to realize there is no one perfect machine. So i need something with some versatility as well. If you could only have one what would you get. Now leaning to the 3401. Thanks in advance as I need to order soon.
