Any tips on what to look for if anything is a common problem for them?

And also I was questioning what are the simplest upgrades for performance on these srt6 for not too much of a pretty penny.... and maybe some of the big upgrades...

any websites?

Obviously I am a newbie to this car but i have always found it to be super clean and cool but I have always had an itch customize cars!

Any help would be great! I'll be here often since it seems this is the car for me from whaty i have been checking out!
