So I am new to the GTR world and still have a lot to learn/research before pulling the trigger on one. I know the used GTR market is kind of insane right now judging from my constant hounding of Autotrader. My criteria is 80k max, 2012+, under 30k miles preferably and clean history. My other options for my first "expensive" car include a late model 2018+ E63s, 2018+GT350 or a gen 3 viper. All things considered i do have to take into account that I live in a town with hail, snow and other anomalies that could affect the roads at times. Vehicle will be purchased in full so not worried about payments but insurance does raise a slight concern due to the conditions of my location. Any input from you seasoned GTR veterans would be highly appreciated especially things to look out for when purchasing, vehicle conditions, mechanical issues i should know of and etc.. My current prospects are a white 2014 out of Portland, and a white 2012 out of Denver. There's very few for sale on the national market right now so you all should know exactly what cars I'm talking about. the 2014 has higher mileage (42k) and engine modifications, and the 2012 has been in a moderate accident according to Carfax. Also a concern I have had is that where i live is 6k+ elevation so would that have any sort of negative affect on the stock engine or modified? Thanks in advance, crazy times we are currently in with the used car market.
