newbie- convience me why?

thinking about buying a 200 mustang or a 2000 camaro, im a ford guy having a hard time deciding wat to get? ive have heard the 4.6l is realy weak. i need some good reasons, like wich would be easier to work on?

I was thinking about getting me a mustang for my next sport. I want to spend 5-10k maybe more if it somthing i really like. Im not realy sure if i want to go 5.0 or 4.6. are the 4.6 a little weak, it seems like a lot of people are putting engine in there 4.6 at 100k or so. more hp the better. I like both body styles

thinking about getting a 4.6, are there any issues that i should know about? Like too much body flex, runing hot or ????
