I expect to drive about 20,000km /year. Don't panic because it's metric. We'll fix that shortly. Ten years is 200,000km. That's 125,000mi.

With the 5.7L engine I'm getting 17.4MPG. That's 7,183 gallons in ten years.

With a 6.1L engine I'd expect about 13MPG. That's 9,615 gallons in ten years.

The difference is about 2,500 gallons. Only the 6.1L engine calls for gas that is *about* 10% more expensive. So let's treat the difference as 2,750 gallons.

Gas in the US is about what... $2.50/gallon?

That's *about* $6,875 over ten years.

US dollars.

An SRT8 would have cost me about $8,000 CDN extra. That and the roughly $7,000 CDN in difference gas is about $15,000 over the ten years of ownership.

I spent $6000 CDN on my body work. End result is that Captain Genius that I am, I'm about $9,000 CDN ahead of the game, over ten years.

I just don't actually get to HAVE an SRT during that ten year period.

These numbers aren't realistic.

I used to have a Daytona and moved up to the SRT when I was presented with an excellent trade-in opportunity. With -IDENTICAL- city driving I get nearly the exact same city mileage with my SRT as I did with my Daytona. After my Daytona was broken-in, and Predatored, my Daytona got averaged about 14.2 mpg... My SRT averages about 13.5 mpg city. Highway my Daytona averaged about 23.5 mpg, my SRT 20.5 mpg. (So average of 19 mpg combined - Daytona vs. 17 combined SRT)

Both cars used premium gas. (Thanks Predator) So no gas price difference here...

So the corrected numbers for the above example:

Daytona:125,000 miles/19mpg = 6,578 gallons

SRT:125,000 miles/17mpg = 7,352 gallons

So 774 gallons, and at $2.50 a gallon, that's just shy of $2,000 over the course of ten years. Now, add in $7-$10 a month for increased insurance cost from an RT to SRT... that's approximately another grand over 10 years.

So $3,000 over ten years. Now compare the trade-in value of a ten-year old RT vs. SRT. The SRT will probably come in $2k better off.

That's makes the real cost of ownership difference about $1000 over ten years, or a measly $100 a year.

I'll take the SRT.
