suzuki 115 vs yamaha 115

[Borussia]

Would like some expert advice on this topic. I am also not sure to either go for a suzuki 115 or a yamaha 115. Would choose the brand which have the best after sales service and reliable technicians. Anyone could suggest a tech for the suzuki and a tech for the Yamaha which are reliable in order to speak to them before deciding? Suzuki are offering 5 years Guarantee vs the 2 year guarantee of the yamaha. Also can anyone help me and guide me through there experience re after sales and techs of both? My friend recommended some one from Suzuki which is highly professional dont know if Dominic Zarb is his name. Do he makes the services if i choose Suzuki? Thanks for your Help.
