^^^^Hey honey the car has this high pitched whine, everytimie i accelerate?!?
hmmm ill have to look into that

 

the G8 ST is on the way...

When looking at city mileage, weight is your enemy. That's why the Corvette does so well despite having a BUNCH of power.

 

that made my mind up pretty quick.

 

In my modded 5.3 ecsb, I avg 16mpg mixed driving with a good size cam, 3600 converter and 4.10 gears.... 20-21 on the hwy around 70-75...

 

How hard are yall driving in stop and go?
I can get 17.5 in town with my truck and thats with the 6.0/4L80E.. 23ish on the interstate.. and she weighs 5000.

Only time i ever dip down in the 14s is when i run it really hard tuning or towing a trailer.

 

I drive mine aggressivly most of the time, but mesa is completely flat, i think thats what helps my numbers

 

its hot as **** in this town( 108 as of right now, and thats livable..) and its cali gas, thats the only two things i can think of...14 when towing a trailer or driving hard, **** i wish that was how it was with me. if i drive her hard or tow a trailer i avg 10.5 to 11

 

My rcsb 4x4 5.3 with 3:72 doesnt even get that bad of mileage in the city running on regular gas, and like most people Im not easy on it

 

If I were you I'd call my insurance company and ask them the prices for a few different cars. The CTS-V may be slightly cheaper on insurance but a WS-6 or GTO will be a bit cheaper then $21,000. Insurance would have to be a lot more to make up the differance.

Also check on the price of parts. If your planning on modding it parts for the caddy might be a bit more.
