I'd take a current 3/4 ton gasser from Ford, GM, or Ram over the 7.3 knowing it would be my DD. Doubt I could get my DW into the 7.3 more than once.
I spent the early '80s driving a 70 Barracuda that cost me 3X purchase price in maintenance costs. The next two times I got into a performance car were a '94 Integra GS-R and then a '98 Lexus GS400. Evolved technology wins every time in my book.
I'm noticing a lot of used 6.7's around here for sale as they get close to the 100K mile mark. Then again my radar is up as I hope to be upgrading from my Expy this time next year.
Best regards,
Chris
