Funny thing is: depending on what year Mustang he had ('04 & earlier) you would've probably kept side by side with him with your "little V6".
Unless he had modded it somehow.........
The V8 'Stangs pre-05 (or '06, can't remember exactly) aren't all that speedy. An SRT would've handed him his as_ on a platter.
I've run against 2 Mustang GT's in my Alabaster White over the years, both '04's, & they were just about the most even races one could imagine. Absolutely side by side, not one budging aganst the other. Both drivers appeared shell-shocked; one of the guys was very cool & I still see him occasionally when heading home. We stopped aong the highway once last year & chatted briefly about cars. He now knows all about Crossfire's & won't mess with the SRT.
