hi i have been a car and truck enthusiast my entire life but mainly have been a GM guy. i know i am gonna get bashed over that but i think i have finally seen the light. my truck is gonna be paid off soon and now its time for a toy. i have been lookin a bit and i am really interested in gettin a mid to late 90's or a early 2000+'s mustang saleen. i love the way they look and the performance. any pros or cons as far as 90's to 2000+'s. are they very mod friendly and what is some good easy and cheap quick mods to do performance wise. also how rare are the 351's i have seen them and they really put out some power but i can never find any for sale. i wanna spend around 20k and i think i can find something good for that. sorry so long but i had to get my points across. thanks for any help.
