If you were buying a car to tune run on a track and do the 1/4 mile you have me sold , but that's not the whole story of owning such a car , from your previous hold threads it's on oohs you have the funds to do what you want to a car and not really worry about warranties.
After my experience of trying to get a non modified car repaired through dealerships modding a new car with 1/4 mile running gear and mods attached it would almost certainly be in possible to get warranty work honoured.
There is a guy on one golf forum who has bought a brand new edition 35 golf dsg and after a month or so complained to the
dealer that his gearbox was playing up , he lived with it , got his car mapped by one the the top 2 tuners (swerves can of worms debate phew !) the gear box fails and VW investigate the car to find said map on his car and invalidate his whole warranty , which is now logged on their database , after some fighting he got his gearbox repaired but his warranty is still void.
PeoPle gamble on discrete mods for warranty claims but unless you have a very sympathetic
dealer things look a lot harder to work honoured when mods are
Obvious.
