ok first off I have owned a gtr and the c7 hands down c7 is a more enjoyable car. gtr is quicker. but you think maint is expensive on c7??? that tells me you have not owned either...gtr needs tires every 12k along with 7000 dollar brake jobs every 12-15k miles along with fluid changes at the same time. so you plan on 12k spent in maint if you keep it for 18k miles assuming your tranmssion makes it till then if that goes along with 15k out of your pocket because they will find a way to pin it on racing the car...hate it when people post because they watched a few u tube videos and read the brochure now there experts
